                                     PART I

Item 1. BUSINESS

GENERAL

    Donaldson Company, Inc. ("Donaldson" or the "Company") was founded in 1915
and organized in its present corporate form under the laws of the State of
Delaware in 1936.

    The Company is a worldwide manufacturer of air cleaners, liquid filters and
exhaust products and accessories for heavy duty mobile equipment; in-plant air
cleaning systems; air intake systems and exhaust products for industrial gas
turbines; and specialized filters for diverse applications. The Company has one
industry segment which consists of the design, manufacture and sale of products
to filter air, sound and liquid.

    The Company's business is not considered to be seasonal. Its principal
products are distributed through multiple channels and primarily sold into these
channels through a direct sales force. Principal methods of competition are
price, geographic coverage, service and product performance. The Company
estimates it has more than 20 competitors in the sale of filtration products and
less than 10 competitors in the sale of acoustical products.

    The table below shows the percentage of total net sales contributed by the
principal classes of similar products for each of the last three fiscal years:

                                           Year Ended July 31
                                    1996          1995          1994

Other                                22%           22%          22%

RAW MATERIALS

    The Company experienced no significant or unusual problems in the purchase
of raw materials or commodities. Donaldson has more than one source of raw
materials essential to its business. The Company is not required to carry
significant amounts of inventory to meet rapid delivery demands or secure
supplier allotments.

PATENTS AND TRADEMARKS

    The Company owns various patents and trademarks which it considers in the
aggregate to constitute a valuable asset. However, it does not regard the
validity of any one patent or trademark as being of material importance.

MAJOR CUSTOMER

    Approximately 12 percent of the Company's 1996 sales were made to
Caterpillar Inc. and subsidiaries ("Caterpillar"). Caterpillar has been a
customer of the Company for many years and it purchases several models and types
of products for a variety of applications. Sales to the U.S. Government do not
constitute a material portion of the Company's business.

BACKLOG

    At August 31, 1996, the backlog of orders expected to be delivered within 90
days was $128,624,000. The backlog at August 31, 1995 was $135,038,000.

RESEARCH AND DEVELOPMENT

    During 1996 the Company spent $15,906,000 on research and development
activities relating to the development of new products or improvements of
existing products or manufacturing processes. The Company spent $14,487,000 in
1995 and $10,873,000 in 1994 on research and development activities. Essentially
all commercial research and development is Company sponsored.

ENVIRONMENTAL MATTERS

    The Company does not anticipate any material effect on its capital
expenditures, earnings or competitive position due to compliance with government
regulations involving environmental matters.

EMPLOYEES

    The Company employed 5,216 persons in worldwide operations as of July 31,
1996.

                                     PART II

Item 5.  MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED
         STOCKHOLDER MATTERS

    On January 12, 1996, the Board of Directors of the company approved the
extension of the benefits afforded by the company's existing rights plan by
adopting a new shareholder rights plan. The new plan, like the existing plan, is
intended to promote continuity and stability, deter coercive or partial offers
which will not provide fair value to all shareholders and enhance the Board's
ability to represent all shareholders and thereby maximize shareholder value.

    Pursuant to the new Rights Agreement, dated as of January 12, 1996, by and
between the company and Norwest Bank Minnesota, National Association, as Rights
Agent, one Right was issued on March 4, 1996 for each outstanding share of
Common Stock, par value $5.00 per share, of the company upon the expiration of
the company's existing rights. Each of the new Rights will entitle the
registered holder to purchase from the company one one-thousandth of a share of
Series A Junior Participating Preferred Stock, without par value, at a price of
$130.00 per one one-thousandth of a share. The Rights, however, will not become
exercisable unless and until, among other things, any person acquires 15 percent
or more of the outstanding Common Stock of the company. If a person acquires 15
percent or more of the outstanding Common Stock of the company (subject to
certain conditions and exceptions more fully described in the Rights Agreement),
each Right will entitle the holder (other than the person who acquired 15
percent or more of the outstanding Common Stock) to purchase Common Stock of the
company having a market value equal to twice the exercise price of a Right. The
new Rights are redeemable under certain circumstances at $.01 per Right and will
expire, unless earlier redeemed, on March 3, 2006.

    The foregoing summary description of the Rights does not purport to be
complete and is qualified in its entirety by reference to the Rights Agreement,
a copy of which is incorporated by reference as Exhibit 4-A to this Annual
Report on form 10-K.

    The information in the sections "NYSE Listing," and "Quarterly Financial
Information (Unaudited)" on page 34, and restrictions on payment of dividends in
Note D, page 28 of the 1996 Annual Report to Shareholders is incorporated herein
by reference. As of September 27, 1996, there were approximately 1,551
shareholders of record of Common Stock.

quarterly period during 1996 and 1995 are as follows:

                                       OF
                             DONALDSON COMPANY, INC.


                                     Offices

    1. The principal office of the corporation shall be in Wilmington, Delaware,
and the resident agent in charge thereof shall be Corporation Service Company.
The corporation may also have an office or offices at such place or places,
within or without the State of Delaware as the Board of Directors may from time
to time designate or the business of the corporation may require.


                                 Corporate Seal

    2. The corporate seal shall have inscribed thereon the name of the
corporation, the year of its incorporation, and the words "Incorporated
Delaware".


                            Meetings of Stockholders

    3. The Annual Meeting of Shareholders for the election of directors and for
the transaction of such other business as may properly come before the meeting
shall be held on the third Friday in November of each year at such hour as may
be specified in the notice of said meeting; provided, should that day be a legal
holiday, then said meeting shall be held on the next succeeding business day
which is not a legal holiday.

    Special meetings of the stockholders may be called at any time by the
chairman of the board or the president and shall be called on the request in
writing or by vote of a majority of the directors.

    All meetings of the stockholders, including meetings for the election of
directors, shall be held at such place or places within or without the State of
Delaware as may from time to time be fixed by the Board of Directors or shall be
specified and fixed in the respective notices or waivers of notices thereof.

    Any proposal for action to be presented by any stockholder at any annual or
special meeting of stockholders, including nominations for director, shall be
out-of-order and shall not be acted upon at such meeting unless such proposal or
nomination was specifically described in the Company's notice to all
stockholders of the meeting and the statement of matters to be acted upon at
such meeting or unless the stockholder intending to present such proposal or
nomination shall have submitted the matter in writing to the secretary and such
writing is received at the principal executive office of the Company not less
than sixty days nor more than 90 days prior to the date of such annual or
special meeting; provided, however, that in the event the meeting is not to be
held on the day set forth in paragraph one of this By-Law 3 and public
disclosure of such meeting date is made less than seventy days prior to the
meeting, the required notice by the stockholder to be timely must be received by
the secretary no later than the close of business on the tenth day following the
date on which such public disclosure was made. The stockholder's notice to the
secretary shall contain such information as will enable a meaningful review of
the matter which the stockholder intends to present at such meeting.

    A complete list of stockholders entitled to vote, arranged in alphabetical
order, shall be prepared by the secretary and shall be open to the examination
of any stockholder at the place of election, for ten days prior thereto, and
during the whole time of the election.

    Except as otherwise provided by statute or by the Certificate of
Incorporation, at each meeting of the stockholders each stockholder having the
right to vote thereat shall be entitled to (i) one vote, in person or by proxy
signed by such stockholder, for each share of common stock of the Corporation
standing in his name, and (ii) such voting rights, if any, as are provided in
the applicable Certificate of Designation, Preferences and Rights with respect
to any series of preferred stock of the Corporation standing in his name, which
voting rights may be exercised in person or by proxy signed by such stockholder,
and in all such instances on the date fixed by the Board of Directors as the
record date for the determination of the stockholders who shall be entitled to
notice of and vote at such meeting; or if no record date shall have been fixed,
then at the close of business on the day next preceding the day on which notice
thereof shall be given. Such right to vote shall be subject to the right of the
board of directors to close the transfer books or to fix a record date for
voting stockholders as hereinafter provided and if the directors shall not have
exercised such right, no share of stock shall be voted on at any election for
directors which shall have been transferred on the books of the corporation
within twenty days next preceding such election.

    Written notice of all meetings shall be given by the secretary not less than
ten nor more than sixty days before the date of the meeting to each stockholder
entitled to vote at such meeting.

    The holders of a majority of the Common Stock outstanding present in person
or represented by proxy shall be requisite to and shall constitute a quorum for
the transaction of business except as otherwise provided by law or by the
Articles of Incorporation as amended or by these By-laws. However, the holders
of the majority of the Common Stock who are present in person or represented by
proxy shall have power to adjourn such meeting from time to time without notice
other than announcement at the meeting until a quorum is secured.


                                    Directors

    4. The property and business of the incorporation shall be managed and
controlled by its board of directors. The number of directors which shall
constitute the whole board shall be such number, not less than three nor more
than fifteen, as may be determined from time to time (i) by the shareholders by
the affirmative vote of the holders of two thirds of the outstanding shares of
all classes of stock of the corporation entitled to vote for the election of
directors (considered for this purpose as one class) or (ii) by the board of
directors by a vote of not less than a majority of all of the directors then in
office. All directors to be elected shall be elected for three year terms
(except as hereinafter provided with respect to directors to fill certain
vacancies) so that approximately one-third of the directors will be elected to
each annual meeting of the shareholders. Each director shall continue in office
until the annual meeting in the year in which his term expires and until his
successor shall have been elected and qualified, or until his death, or until he
shall resign or have been removed by the vote of the holders of a majority of
the outstanding shares of capital stock of all classes of the corporation
entitled to vote in the election of directors at a special meeting of the
shareholders called for that purpose.

    Any vacancies in the board of directors from any cause, including vacancies
created by increase in the number of directors, may be filled either by a
majority of the then qualified directors, even though less than a quorum, or by
the stockholders. Each director so chosen shall hold office for the unexpired
term of the director whose place shall be vacant, providing that each director
so chosen to fill a vacancy created by increase in the number of directors shall
be elected for an appropriate term so that approximately one-third of the
directors will be elected at each annual meeting of the stockholders thereafter.

    Directors shall be bonafide owners of at least one hundred (100) shares of
this corporation's stock, shall not stand for election or re-election after
attaining the age of sixty-eight and shall offer their resignation from the
Board at such time as they may change their basic business or professional
activity or affiliation; provided, however, that non-employee directors need not
offer such resignation in the event of normal retirement. Non-employee directors
continuous membership on the board of directors shall be limited to five
consecutive three year terms.


                               Powers of Directors

    5. The board of directors shall have, in addition to such powers as are
hereinafter expressly conferred on it, all such powers as may be exercised by
the corporation, subject to the provisions of the statute, the certificate of
incorporation and the by-laws.

    The board of directors shall have power:

    To purchase or otherwise acquire property, rights or privileges for the
corporation, which the corporation has power to take, at such prices and on such
terms as the board of directors may deem proper.

    To pay for such property, rights or privileges in whole or in part with
money, stock, bonds, debentures or other securities of the corporation, or by
the delivery of other property of the corporation.

    To create, make and issue mortgages, bonds, deeds of trust, trust agreements
and negotiable or transferable instruments and securities, secured by mortgages
or otherwise, and to do every other act and thing necessary to effectuate the
same.

    To appoint agents, clerks, assistants, factors, employees and trustees, and
to dismiss them at its discretion, to fix their duties and emoluments and to
change them from time to time and to require security as it may deem proper.

    To confer on any officer of the corporation the power of selecting,
discharging or suspending such employees.

    To determine by whom and in what manner the corporation's bills, notes,
receipts, acceptances, endorsements, checks, releases, contracts or other
documents shall be signed.


                              Meetings of Directors

    6. Immediately after each annual election of directors, the directors shall
meet for the purpose of organization, the election of officers and the
transaction of other business at such place as shall be specified in the notice
of such meeting provided as hereinafter established for either regular or
special meetings.

    The board of directors may provide by resolution, the time and place, either
at the general office of the company or elsewhere, for the holding of regular
meetings without other notice than such resolution.

    Special meetings of the directors may be called at any time by the chairman
of the board, the president or any vice president who is also a director and
shall be called on the written request of any two directors. Notice of such a
special meeting shall be in writing sent to each director at his residence or
usual place of business two days prior thereto.

    Special meetings of the directors may be held within or without the State of
Delaware at such place as is indicated in the notice or waiver of notice
thereof.

    A majority of the directors shall constitute a quorum, but a smaller number
may adjourn from time to time, without further notice, until a quorum is
secured.


                         Executive and Other Committees

    7. The board of directors may, by resolution or resolutions passed by a
majority of the whole board, designate an executive committee and one or more
other committees, each to consist of two or more of the directors of the
corporation.

    The executive committee shall not have authority to make, alter or amend the
by-laws, but shall exercise all other powers of the board of directors between
the meetings of said board, except the power to fill vacancies in their own
membership, which vacancies shall be filled by the board of directors.

    The executive committee shall meet at stated times or on notice to all by
any of their own number. It shall fix its own rules of procedure. A majority
shall constitute a quorum, but the affirmative vote of a majority of the whole
committee shall be necessary in every case.

    The executive committee shall keep regular minutes of its proceedings and
report the same to the board of directors.

    Such other committees shall have and may exercise the powers of the board of
directors to the extent provided in such resolution or resolutions.


               Compensation of Directors and Members of Committees

    8. Directors and members of standing committees shall receive such
compensation for attendance at each regular or special meeting as the board
shall from time to time prescribe.


                           Officers of The Corporation

    9. The officers of the corporation shall be the chairman of the board of
directors (if one is elected by the board of directors), the president, one or
more vice presidents, a secretary, a treasurer and such other officers as may
from time to time be elected by the board of directors.

    The officers of the corporation shall hold office until their successors are
elected and qualify. An officer elected by the board of directors may be removed
either with or without cause at any time by the affirmative vote of a majority
of the whole board of directors. Such removal, however, shall be without
prejudice of the contract rights of the person so removed. If the office of any
officer becomes vacant for any reason, the vacancy may be filled by the
affirmative vote of a majority of the whole board of directors.


              Duties of the Chairman of the Board and the President

    10. The chairman of the board of directors, if one is elected, shall preside
at all meetings of the shareholders and directors and shall have such other
duties as may be prescribed from time to time by the board of directors.

    In the absence of the chairman of the board of directors, the president
shall preside at all meetings of the shareholders and directors and shall have
such other duties as may be prescribed from time to time by the board of
directors.

    If the chairman of the board of directors is elected, the board of directors
shall designate which of the chairman of the board of directors or the president
is the chief executive officer of the corporation, and shall provide for the
division of executive duties and responsibilities between those two officers. If
the chairman of the board of directors shall not be elected, the president shall
be the chief executive officer of the corporation and shall have general and
active management of the business of the corporation.


                                 Vice President

directors, the executive committee and standing committees. He shall act as

    16. Certificates of stock shall be signed by the President or a Vice
President and the Treasurer, Assistant Treasurer, Secretary or Assistant

In case any officer, transfer agent or registrar who has signed or whose
facsimile signature has been placed upon any such certificate shall thereafter
have ceased to be such officer, transfer agent or registrar before such
certificate is issued, such certificate may nevertheless be issued by the
corporation with the same effect as though the person who signed such
certificate, or whose facsimile signature shall have been placed thereupon, were
such officer, transfer agent or registrar at the date of issue. If a certificate
of stock be lost, mutilated or destroyed, another may be issued in its stead
upon proof of such loss, mutilation or destruction, and the giving of a bond of
indemnity in form, substance and amount satisfactory to the corporation and to
the Transfer Agent and Registrar, if any, of such stock, provided that, if there
be no Transfer Agent or Registrar for the class of stock of which the
certificate be lost, mutilated or destroyed, the Board of Directors may waive
the requirement of a bond indemnity if in its judgment such waiver is warranted
by the circumstances.


                                Transfer of Stock

    17. All transfers of stock of the corporation shall be made upon its books
by the holder of the shares in person or by his lawfully constituted
representative, upon surrender of certificates of stock for cancellation.

effect cancellation of the certificate representing the abandoned shares and
cause transfer thereof to such state by means of delivery of a new certificate
in the name of such state.


                            Closing of Transfer Books

    18. The Board of Directors shall have power to close the stock transfer book
for a period not exceeding sixty days preceding the date of any meeting of
stockholders or the date for payment of any dividend or the date for allotment
of rights or the date when any change, conversion or exchange of stock shall go
into effect or in connection with obtaining the consent of stockholders for any
purpose. If the stock transfer book is closed preceding the date of any meeting
of stockholders, such book shall be closed for at least ten days immediately
preceding such meeting. In lieu of closing the stock transfer book, the Board of
Directors may fix, in advance, a record date, which shall not be more than sixty
nor less than ten days before the date of any meeting of stockholders, nor more
than sixty days prior to any other action, for the determination of stockholders
entitled to notice of, and to vote, at any such meeting or any adjournment
thereof, or entitled to receive payment of any such dividend, or to any such
allotment of rights, or to exercise the rights in respect of any such change,
conversion or exchange of stock or to give such consent, and in such case such
stockholders and only such stockholders as shall be stockholders of record on
the date so fixed shall be entitled to such notice of, and to vote at such
meeting and any adjournment thereof, or to receive payment of such dividend, or
to receive such allotment of rights, or to exercise such rights, or to give such
consent, as the case may be, notwithstanding any transfer of any stock on the
books of the Corporation after such record date fixed as aforesaid.


                             Stockholders of Record

    19. The corporation shall be entitled to treat the holder of record of any
share or shares as the holder in fact thereof and accordingly shall not be bound
to recognize any equitable or other claim to or interest in such share on the
part of any other person whether or not it shall have express or other notice
thereof, save as expressly provided by the laws of Delaware.


                                   Fiscal Year

    20. The fiscal year of the corporation shall begin on the first day of
August in each year, commencing with the year 1956.


                                    Dividends

    21. Dividends upon the capital stock may be declared by the board of
directors at any regular or special meeting and may be paid in cash or in
property or in shares of the capital stock. Before paying any dividend or making
any distribution of profits, the directors may set apart out of any of the funds
of the corporation available for dividends a reserve or reserves for any proper
purpose and may alter or abolish any such reserve or reserves.


                                Checks for Money

                                Books and Records

    23. The books, accounts and records of the corporation except as otherwise
required by the laws of the State of Delaware, may be kept within or without the
State of Delaware, at such place or places as may from time to time be
designated by the By-laws or by resolution of the directors.


                                     Notices

    24. Notice required to be given under the provisions of these By-laws to any
director, officer or stockholder shall not be construed to mean personal notice,
but may be given in writing by depositing the same in a post office or
letter-box, in a post-paid sealed wrapper, addressed to such stockholder,
officer or director at such address as appears on the books of the corporation,
and such notice shall be deemed to be given at the time when the same shall be
thus mailed. Any stockholder, officer or director may waive, in writing, any
notice required to be given under these By-laws, whether before or after the
time stated therein.


                              Amendments of By-laws

    25. Except as hereinafter stated, these By-laws may be amended, altered,
repealed or added to by the shareholders by the affirmative vote of a majority
of the outstanding shares entitled to vote on the matter, or by the board of
directors by a majority of the directors then in office, at any regular meeting
or at any special meeting called for that purpose. Provided that, any amendment,
alteration or repeal of, or addition to, the first paragraph of By-law 4 or this
sentence of By-law 25 by shareholders shall require the affirmative vote of
66-2/3% of the outstanding shares of capital stock of all classes of the
corporation entitled to vote generally for the election of directors, considered
for this purpose as one class.


                   Indemnification of Directors and Officers

    26. The Corporation shall indemnify such persons, for such liability or
expense, in such manner, under such circumstances, and to the fullest extent
permitted by Section 145 of the Delaware General Corporation Law, as now enacted
or hereafter amended. The Board of Directors may authorize the purpose and
maintenance of insurance for the purpose of such indemnification.


                                Emergency Bylaws

    27. The emergency Bylaws provided in this article shall be operative during
any emergency resulting from an attack on the United States or on a locality in
which the corporation conducts its business or customarily holds meetings of its
board of directors or its shareholders, or during any nuclear or atomic
disaster, or during the existence of any catastrophe, or other similar emergency
condition, as a result of which a quorum of the board of directors or a standing
committee thereof cannot readily be convened for action. Upon termination of
such emergency, these Emergency Bylaws shall cease to be operative unless and
until another such emergency shall occur. When operative, the provisions of
these Emergency Bylaws shall prevail over any contrary provision in the
certificate of incorporation or other bylaws of the corporation.

    During any such emergency:

        (a) A meeting of the board of directors may be called by any officer or
    any director of the corporation.

        (b) Notice of the time and place of such directors' meeting shall be
    given by such person calling the meeting or by any officer of the
    corporation; provided, however, that any such notice need be given only to
    such of the directors and other persons as it may be feasible to reach at
    that time, and by such means as may be feasible at that time, including, but
    not limited to radio and publication. Notice shall be similarly given, to
    the extent feasible, to all persons referred to in paragraph (c) of these
    Emergency Bylaws. Notice shall be given at least two days before the
    meeting, if feasible in the judgment of the person giving or authorizing the
    giving of the notice, and otherwise on any shorter time that such person may
    deem necessary under the circumstances.

        (c) At any meeting of the board of directors, a quorum shall consist of
    a majority of the number of directors fixed at that time. If the directors
    present at any particular meeting shall be fewer than the number required
    for such quorum, other persons present, to the number necessary to make up
    such quorum, shall be deemed directors for that particular meeting to be
    determined by the following provisions and in the following order of
    priority:

        (1) The persons who are designated on a priority list, which shall have
            been approved by the board of directors before the emergency, such
            persons to be taken in the order of priority provided by the list
            and subject to such conditions as may be established therein; or

        (2) In the absence of sufficient persons designated in such list, all
            officers of the corporation in order of their seniority of first
            election to an office or the corporation.

        (d) The board of directors constituted as provided in these Emergency
    Bylaws may exercise the full power and authority of the regular board of
    directors.

        (e) The board of directors may provide, and from time to time modify,
    lines of succession in the event that during such emergency any or all
    officers or agents of the corporation shall for any reason be rendered
    incapable of discharging their duties.

        (f) The necessity of holding an annual meeting of shareholders may be
    suspended for a period not to exceed one year if, in the sole judgment of
    the board of directors, the holding of such meeting is not feasible under
    the circumstances prevailing at the time such annual meeting would
    ordinarily be held; provided, however, that the bylaw provisions for the
    calling of a special meeting of shareholders shall remain in effect and any
    special meeting called during said suspension shall have as an item of
    business the election of a board of directors.

        (g) No officer, director or employee acting in accordance with these
    Emergency Bylaws shall be liable except for willful misconduct.

MANAGEMENT'S DISCUSSION AND ANALYSIS
Donaldson Company, Inc. and Subsidiaries


RESULTS OF OPERATIONS

1996 COMPARED TO 1995

     Record 1996 net sales of $758.6 million were up 8 percent from prior-year
sales of $704.0 million. For the year, Engine Products sales were up 7 percent
and Industrial Products sales were up 9 percent.
     
     Domestic Engine products sales were up 12 percent, primarily from increased
shipments to original equipment manufacturers (OEMs). Weakness in the heavy duty
transportation market was more than offset by new business in the automotive and
defense markets. In addition, domestic aftermarket sales increased 7 percent
year over year. Domestic Industrial Products sales increased 2 percent led by
strong sales in the Torit Products (dust collection) market offset by lower
sales in high purity products.

     Overseas sales increased almost 7 percent - 9 percent in local currencies
- -- primarily due to increased net sales in Europe and Hong Kong. Net sales in
Japan decreased 12 percent year over year. Overseas Industrial Products sales
increased 20 percent, primarily due to higher shipments of Torit Products and
gas turbine systems products in Europe and increased sales of high purity
products and gas turbine systems in Hong Kong. High purity product sales in Hong
Kong benefited from the company's decision in early 1996 to consolidate all disk
drive filter production in Hong Kong; clean room operations in the U.S. and
England were discontinued as part of this change. Engine Products sales were
flat compared to the prior year as increased shipments to European OEMs were
offset by lower OEM sales in Japan. In 1996, overseas sales totaled 37 percent
of consolidated net sales, down 1 percentage point from 38 percent in 1995.

     Record net earnings for 1996 of $43.4 million were up 13 percent from $38.5
million in the prior year. Increased net sales and improvements in the gross
margin were the primary reasons for the higher earnings. Overseas operating
income totaled approximately 53 percent of consolidated operating income
compared to 54 percent in 1995.

     Gross margin for 1996 increased to 29.4 percent compared to 28.1 percent in
the prior year. Increased manufacturing efficiencies gained by higher operating
levels and lower raw material prices in 1996 were slightly offset by higher
obsolete inventory expense and a $2.0 million impaired asset write-down. Margins
improved in Japan's transportation and Industrial Products markets, and Europe's
high purity products and Torit Products markets. In addition, margin
improvements were noted in all domestic markets. Offsetting these gains were
margin declines in Hong Kong's Industrial Products markets as well as Europe's
OEM and gas turbine systems markets.

     Operating expenses as a percentage of sales for 1996 and 1995 were 19.4
percent and 18.8 percent, respectively. 1996 operating expenses totaled $147.2
million compared to $132.4 million in 1995, which reflects an increase of $14.8
million, or 11 percent. Selling expenses in 1996 increased $6.1 million
primarily due to the higher sales levels while general and administrative
expenses increased $7.2 million due to higher medical expenses and increased
warranty accruals on new and existing product lines.

     Interest expense declined $0.2 million, or 6 percent, primarily due to the
decline in total debt. Other expense totaled $1.6 million in 1996 compared to
other income of $0.7 million in the prior year. The $2.3 million change is
primarily due to a $1.1 million increase in foreign exchange loss, a $0.2
million decline in interest income, a $0.7 million increase in charitable
contributions, and a $0.3 million charge related to the sale of our Brazilian
operation. Favorable earnings at AFSI, a joint venture with Caterpillar, Inc.,
offset $0.6 million of the unfavorable other expense variance.
     
     The effective income tax rate of 38.9 percent in 1996 was flat compared to
39.0 percent in 1995. For both years, the company's effective rate is higher
than the statutory federal rate due to higher effective overseas, state and
local taxes.

     During the fourth quarter of 1996, the company sold the operations and
substantially all of the assets related to its Brazilian subsidiary. The sale
did not result in any material charge or credit to earnings. Net sales for this
operation totaled $3.0 million in 1996 compared to $6.3 million in 1995.
Operating losses for 1996 and 1995 were $1.5 million and $0.3 million,
respectively.

     Hard order backlogs, goods scheduled for delivery in 90 days, were $121.9
million and $134.1 million at July 31, 1996 and 1995, respectively. A $2.2
million increase in worldwide Engine Products backlog was offset by a $13.5
million decline in worldwide gas turbine systems backlog. Backlogs, orders and
shipments in the gas turbine business segment typically fluctuate widely from
period to period; the most recent decline in backlogs is consistent with
historical patterns and does not indicate any fundamental change in the current
market conditions. Total backlogs of $203.3 million were down 5 percent from the
prior year-end, primarily due to lower gas turbine systems orders.

1995 COMPARED TO 1994

     1995 net sales of $704.0 million were up 19 percent from prior-year sales
of $593.5 million. For the year, Engine Products sales were up 20 percent and
Industrial Products sales were up 16 percent.

     Domestic Engine Products sales were up 12 percent, primarily from increased
shipments to OEMs. Industrial


                                       18


Products sales growth of 15 percent was primarily led by strong sales in our
Torit Products market.
     
     Overseas sales in 1995 increased 32 percent -- 21 percent in local
currencies -- generally due to the improving economies in Europe and Japan.
Overseas Engine Products sales were up 36percent, primarily due to strong sales
in Europe and Japan. Industrial Products sales increased 23 percent, reflecting
increased Torit Products sales in Europe, Japan and South Africa. In 1995,
overseas sales totaled 38 percent of consolidated net sales, up 4 percentage
points from 34 percent in 1994.
     
     Net earnings for 1995 totaled $38.5 million, up significantly from $31.9
million in the prior year. Increased sales levels and operating efficiencies
were the primary reasons for the gain in 1995. Overseas operating income totaled
approximately 54 percent of consolidated operating income, up from 50 percent
the prior year.
     
     Gross margin for 1995 was unchanged at 28.1 percent compared to 1994.
Increased manufacturing efficiencies gained by higher operating levels in 1995
were offset by a $1.4 million asset write-down, increased plant repairs and
increased obsolete inventory expense. Margin improvements in defense and both
domestic and overseas aftermarkets were offset by declines in worldwide
Industrial Products margins.
     
     In 1995, the company recorded a $1.4 million charge to provide for the
residual net book value of certain production assets. In the prior year, the
company wrote down certain of its Brazilian manufacturing capital assets by $3.2
million.
     
     Operating expenses as a percentage of sales for 1995 and 1994 were 18.8
percent and 19.3 percent, respectively. Full year spending for 1995 totaled
$132.4 million compared to $114.5 million in 1994, which reflects an increase of
$17.9 million, or 16 percent. Most of the increased expense resulted from higher
selling expenses related to the higher sales level in 1995. In addition, general
and administrative expenses reflect the impact of the acquisition of 100 percent
of our Mexican joint venture and increased costs from the upgrade of the
company's information systems.
     
     Interest expense declined $0.3 million, or 8 percent, in the year primarily
due to the decrease in long-term debt. Other income totaled $0.7 million in 1995
compared to $1.5 million in 1994. The $0.8 million decline is primarily due to
lower earnings at AFSI, and an increase in the contribution to the Donaldson
Foundation.
     
     The effective income tax rate in 1995 was 39.0 percent, compared to 36.3
percent in 1994. The increase in 1995 was primarily the result of increased
profitability in Germany and Japan, the company's highest taxed subsidiaries.

     Total backlogs of $214.2 million were up 35 percent from the prior
year-end. Strong order increases were reported for domestic defense and
worldwide diesel engine OEMs. In addition, worldwide gas turbine systems backlog
increased 23 percent. Hard order backlogs, goods scheduled for delivery in 90
days, of $134.1 million were up 26 percent compared to the prior year, primarily
due to strong worldwide OEM orders.


LIQUIDITY AND CAPITAL RESOURCES

FINANCIAL CONDITION

     At July 31, 1996, the company's capital structure comprised $13.1 million
of current debt, $10.0 million of long-term debt and $228.9 million of
shareholders' equity. The ratio of long-term debt to total long-term capital was
4.2 percent, compared with 4.4 percent at July 31, 1995.
     
     Total debt decreased $7.8 million during 1996 to $23.2 million. Most of the
decrease resulted from the company's decision to discontinue the use of
short-term debt to hedge foreign currency denominated account receivables at
certain of its European subsidiaries.

     In December 1995, the company entered into a five- year multi-currency
revolving credit facility totaling $100.0 million with a group of international
banks, led by Citibank as agent. There were no amounts outstanding under this
facility at July 31, 1996. The company believes that the combination of present
capital resources, internally generated funds, and unused financing sources are
more than adequate to meet cash requirements for 1997.

     Shareholders' equity increased $7.7 million in 1996 to $228.9 million. The
increase was primarily due to net earnings of $43.4 million, offset by $23.1
million of treasury stock repurchases, an $8.8 million decrease in the
cumulative translation adjustment and $7.7 million of dividend payments.


CASH FLOWS

     During 1996, $76.9 million of cash was generated from operating activities,
compared with $52.9 million in 1995 and $31.4 million in 1994. The increase in
1996 was largely the result of increased net earnings, higher depreciation and
amortization expense and a significant increase in trade accounts payable,
accruals and income taxes payable. Significant uses for cash included $39.3
million of capital expenditures, $23.1 million of treasury stock repurchases and
$7.7 million of dividend payments. Cash and cash equivalents increased $2.4
million during 1996.

     Capital expenditures for property, plant and equipment totaled $39.3
million in 1996, compared to $25.3 million in 1995 and $24.6 million in 1994.
Significant additions in 1996 include the upgrade of information


                                       19


systems in the U.S., the construction of a new production line at the Stevens
Point, Wisconsin facility, the upgrade of equipment at the Nicholasville,
Kentucky and Grinnell, Iowa facilities, the construction of a second Baldwin,
Wisconsin manufacturing facility and the construction of a new manufacturing
facility in Brugge, Belgium.

     Capital spending in 1997 is planned to be $53.0 million. Significant
planned expenditures include the further upgrade of U.S. information systems,
and new production lines for liquid aftermarket products in Stevens Point,
Wisconsin and Aquascalientes, Mexico. It is anticipated that 1997 capital
expenditures will be financed primarily through funds from operations.


DIVIDENDS

     The company's dividend policy is to maintain a payout ratio which allows
dividends to increase with the long-term growth of earnings per share, while
sustaining dividends in down years. The company's dividend payout ratio target
is 20 to 25 percent of the average earnings per share of the last three years.
The current quarterly dividend of 8 cents per share equates to 22 percent of the
1994 through 1996 average net earnings per share.


SHARE REPURCHASE PLAN

     In 1996, the company repurchased 0.9 million shares of common stock on the
open market for $23.1 million, at an average price of $24.83 per share. The
company repurchased 0.6 million shares for $14.7 million in 1995 and 0.8 million
shares for $17.5 million in 1994. At July 31, 1996, the company has
authorization to repurchase an additional 1.6 million shares. Depending on
market conditions, the company expects to maintain or increase its level of
treasury stock repurchases in 1997.


CHANGE IN ACCOUNTING PRINCIPLES

     In 1996, the company adopted Financial Accounting Standards Board Statement
No. 121, "Accounting for the Impairment of Long-Lived Assets," which requires
losses on impairment of long-lived assets used in operations to be recorded when
indicators of impairment are present and the undiscounted cash flows estimated
to be generated by those assets are less than the assets' carrying amounts. The
adoption had no impact on the financial statements.

     Effective August 1, 1993, the company adopted Financial Accounting
Standards Board Statement No. 109 (FAS 109), which requires adoption of a
liability approach to account for the effects of income taxes. The cumulative
effect of adopting FAS 109 was to increase 1994 net earnings by $2.2 million, or
8 cents per share.

     In October 1995, the Financial Accounting Standards Board issued Statement
No. 123 (FAS 123), "Accounting for Stock Based Compensation." FAS 123 encourages
companies to adopt a fair value based method of accounting for employee stock
options, but allows companies to continue to measure compensation cost for such
plans as it is measured currently. The company plans to continue to use the
current method of accounting for stock compensation in 1997, but will adopt the
disclosure requirements of FAS 123, making pro forma disclosure of net earnings
and earnings per share as if the fair value based method had been applied. FAS
123 will have no impact on the company's financial position or results of
operations.


FOREIGN CURRENCY EFFECTS

     In 1996, the U.S. dollar was generally stronger relative to the currencies
of foreign countries where the company operates. A stronger dollar generally has
a negative impact on overseas results because foreign-exchange denominated
earnings translate into less U.S. dollars; a weaker dollar generally has a
positive translation effect.
     
     It is not possible to determine the true impact of foreign currency
translation changes; however, the direct effect on net sales and net earnings
can be estimated. For 1996, the stronger U.S. dollar decreased net sales by $7.4
million and decreased net earnings by $0.6 million. During 1995, the generally
weaker U.S. dollar increased net sales by $21.9 million and net earnings by $0.4
million.

1995, and the related consolidated statements of earnings, changes in
shareholders' equity and cash flows for each of the three years in the period
ended July 31, 1996. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly, 
in all material respects, the consolidated financial position of Donaldson
Company, Inc. and subsidiaries at July 31, 1996 and 1995, and the consolidated
results of their operations and their cash flows for each of the three years
in the period ended July 31, 1996, in conformity with generally accepted
accounting principles.

     As discussed in Note H, in 1994 the Company changed its method of
accounting for income taxes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Donaldson Company, Inc. and Subsidiaries

NOTE A: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION: The consolidated financial statements include the
accounts of Donaldson Company, Inc. and all majority-owned subsidiaries. All
significant intercompany accounts and transactions have been eliminated. The
accounts of overseas subsidiaries are included for fiscal years ended June 30.
Certain amounts in prior periods have been reclassified to conform to the
current presentation.

USE OF ESTIMATES: Preparing financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

FOREIGN CURRENCY TRANSLATION: Foreign assets and liabilities are generally
translated using the year-end rates of exchange. Results of operations are
translated using the average rates prevailing throughout the period. Translation
gains or losses, net of applicable deferred taxes, are accumulated as a separate
component of shareholders' equity. Foreign currency transaction (losses)/gains
of $(1,067,000), $47,000 and $(1,337,000), in 1996, 1995 and 1994, respectively,
are included in earnings before income taxes.

CASH EQUIVALENTS: The company considers all highly liquid investments with a
maturity of 90 days or less when purchased to be cash equivalents. Cash
equivalents are carried at cost which approximates market value.

INVENTORIES: Inventories are stated at the lower of cost or market, determined
by the last-in, first-out (LIFO) method, except for certain of the company's
overseas subsidiaries which use the first-in, first-out (FIFO) method.
Inventories valued at LIFO were 55 and 56 percent of total inventories at July
31, 1996 and 1995, respectively.
     
     The current cost of inventories valued under the LIFO method exceeded their
LIFO carrying values by $19,909,000 and $20,557,000 at July 31, 1996 and 1995,
respectively.

PROPERTY, PLANT AND EQUIPMENT: Property, plant and equipment is stated at cost.
Depreciation is computed principally by use of declining balance methods on
facilities and equipment acquired on or prior to July 31, 1992. For financial
reporting purposes, the company adopted the straight line depreciation method
for all property acquired after July 31, 1992. Depreciation expense includes the
amortization of capital lease assets.

     The company adopted Financial Accounting Standards Board Statement No. 121,
"Accounting for the Impairment of Long-Lived Assets," which requires losses on
impairment of long-lived assets used in operations to be recorded when
indicators of impairment are present and the undiscounted cash flows estimated
to be generated by those assets are less than the assets' carrying amounts. The
adoption had no impact on the financial statements.

     The estimated useful lives of property, plant and equipment are as follows:

     Buildings ..............................   10 to 40 years
     Machinery and Equipment.................    3 to 10 years

INCOME TAXES: Income taxes are provided based on earnings reported for financial
statement purposes. The provision for income taxes differs from the amounts
currently payable because of temporary differences in the recognition of certain
assets and liabilities for financial reporting and tax reporting purposes.
Deferred taxes are recorded based on enacted tax laws and tax rates. Changes in
enacted tax rates are reflected in the income tax provision as they occur.

     Effective August 1, 1993, the company adopted Financial Accounting
Standards Board Statement No. 109, "Accounting for Income Taxes" (FAS 109). As
permitted under the Statement, prior years' financial statements have not been
restated.

NET EARNINGS PER SHARE: Net earnings per common share is based on the weighted
average number of common shares and share equivalents outstanding during the
respective years.

TREASURY STOCK: Repurchased Common Stock is stated at cost and is presented as a
separate reduction of shareholders' equity.


                                       26


STOCK OPTIONS: In October 1995, Financial Accounting Standards Board Statement
No. 123 (FAS 123), "Accounting for Stock-Based Compensation" was issued, which
is effective for fiscal years beginning after December 15, 1995. FAS 123
encourages companies to adopt a fair value based method of accounting for
employee stock options, but allows companies to continue to account for those
plans using the accounting prescribed by APB Opinion 25, "Accounting for Stock
Issued to Employees." The company will adopt the disclosure requirements of FAS
123 in 1997 and plans to continue accounting for stock compensation using APB
25, making pro forma disclosures of net earnings and earnings per share as if
the fair value based method had been applied.

NOTE B: ACQUISITIONS AND DIVESTITURE

ACQUISITIONS

     During 1996, the company acquired all of the common stock of Tecnov S.A., a
French manufacturer of heavy duty exhaust mufflers, and the company invested in
a Torit Products manufacturer in the People's Republic of China.
     
     During 1995, the company acquired the remaining 50 percent of Donaldson
Micro Pore Mexico, S.A. de C.V., obtained a 20 percent interest in an Indonesian
filter manufacturer and purchased an additional 9.9 percent in its Australian
Torit Products distributor.

     During 1994, the company increased its investment in Donaldson Micro Pore
Mexico, S.A. de C.V., from 40 percent to 50 percent, obtained a 40 percent
interest in an Australian Torit Products distributor, invested in a gas turbine
system joint venture in India, and completed an acquisition of a high purity
products materials supplier located in the United States.

     All acquisitions have been accounted for as purchases and, accordingly,
their net assets and operating results are included in the company's financial
statements from the respective dates of acquisition. The pro forma impact of the
acquisitions on the company's results of operations for all years presented was
not material.

DIVESTITURE

     During the fourth quarter of 1996, the company sold the operations and
substantially all the assets related to its Brazilian subsidiary, Donaldson do
Brasil, Ltda., (DBL). The sale did not result in any material charge or credit
to earnings. DBL's results of operations prior to the divestiture date have been
included in the company's consolidated results of operations.

NOTE C: SHORT-TERM DEBT

The company has a five-year $100 million multi-currency credit facility. The
interest rate for borrowings is based on certain of the company's adjusted
leverage and debt to capitalization ratios at various points in time. Facility
fees and other fees on the entire loan commitment are payable for the duration
of this facility. There were no amounts outstanding under lines of credit at
July 31, 1996 and 1995.

     Overseas subsidiaries may borrow under various uncommitted facilities. As
of July 31, 1996 and 1995, borrowings under these facilities were $8,916,000 and
$17,802,000, respectively. The weighted average interest rate on short-term debt
outstanding at July 31, 1996 and 1995 was 5.6 percent and 7.1 percent,
respectively.

NOTE D: LONG-TERM DEBT

Long-term debt consists of the following:

$2,906,000 in 1996, 1995 and 1994, respectively.

     Certain note agreements contain debt covenants related to working capital
levels and limitations on indebtedness. Further, the company is restricted from
paying dividends or repurchasing Common Stock if its tangible net worth (as
defined) does not exceed certain minimum levels. At July 31, 1996, under the
most restrictive agreement, tangible net worth exceeded the minimum by
$71,964,000.

NOTE E: CAPITALIZED LEASES

     The company leases several production facilities under long-term leases and
has the option to purchase the facilities for a nominal cost at the termination
of the lease.

     Included in property, plant and equipment are the following assets held
under capital leases:

NOTE F: EMPLOYEE BENEFIT PLANS

PENSION PLANS: Donaldson Company, Inc. and certain of its subsidiaries have
defined benefit pension plans for substantially all hourly and salaried
employees. The domestic plans provide benefits based on the employee's years of
service and compensation during the years immediately preceding retirement. The
overseas plans generally provide similar types of benefits. 
     
     The company's general funding policy is to make contributions as required 
by applicable regulations. The assets are primarily invested in diversified
portfolios comprised of equity and debt securities. 
     
     Cost for the company's pension plans includes the following components:

EMPLOYEE STOCK OWNERSHIP PLAN: In 1987, the company established an Employee
Stock Ownership Plan (ESOP) for eligible U.S. employees. The ESOP borrowed
$21,000,000 from the company to purchase 3,600,000 newly issued shares of Common
Stock. These shares are held in trust and are issued to employees' accounts in
the ESOP as the loan is repaid over 10 years. At July 31, 1996 and 1995,
3,314,364 and 2,928,170 shares have been allocated to employees. The loan
obligation of the ESOP is considered unearned employee benefit expense and, as
such, is recorded as a reduction of the company's shareholders' equity. The
company's contributions to the ESOP, plus dividends paid on unallocated shares
held by the ESOP, are used to repay the loan principal and interest. Both the
loan obligation and the unearned benefit expense are reduced by the amount of
loan principal repayments made by the ESOP. The ESOP contribution expense
totaled $2,453,000, $2,130,000 and $2,020,000 in 1996, 1995 and 1994,
respectively.

NOTE G: EMPLOYEE INCENTIVE PLANS

     In November 1991, shareholders approved the 1991 Master Stock Compensation
Plan. The Plan extends through December 2001 and allows for the granting of
nonqualified stock options, incentive stock options, restricted stock, stock
appreciation rights (SARs), dividend equivalents, dollar-denominated awards and
other stock-based awards.
     
     The 1980 Master Stock Compensation Plan allows for the granting of
nonqualified stock options and incentive stock options.
     
     Both plans allow for the granting of performance awards to a limited number
of key executives. The awards are payable in Common Stock and are based on a
formula which measures performance of the company over a three- year period.
Performance award expense totaled $2,135,000, $2,064,000 and $57,000 in 1996,
1995 and 1994, respectively.
     
     Options under both Plans are granted to key employees at or above 100
percent of the market price at the date of grant. Options are exercisable for up
to 10 years from the date of grant.

     The number and option  price of options  granted  under these plans were as
follows:

exercisable, respectively. Shares reserved at July 31, 1996 for outstanding
options and future grants were 2,908,433.

NOTE H: INCOME TAXES

     Effective August 1, 1993, the company changed its method of accounting for
income taxes to comply with Financial Accounting Standards Board Statement No.
109, "Accounting for Income Taxes" (FAS 109). The statement requires a liability
approach for computing income taxes. As permitted under the statement, prior
years' financial statements have not been restated. The cumulative effect of
adopting FAS 109 was to increase 1994 net earnings by $2,206,000 ($.08 per
share).

     The components of earnings before income taxes are as follows:

     At July 31, 1996, certain overseas subsidiaries had available net operating
loss carryforwards of approximately $4,569,000 to offset future taxable income.
The majority of such carryforwards expire after 2001. Unremitted earnings of
overseas subsidiaries amounted to approximately $75,318,000 at July 31, 1996.
Those earnings are intended to be indefinitely reinvested and, accordingly, no
income taxes have been provided. If a portion were to be remitted, income tax
credits would substantially offset any resulting tax liability. It is not
practicable to estimate the amount of unrecognized taxes on these undistributed
earnings due to the complexity of the computation.
     
     The company made cash payments for income taxes of $20,516,000,
$21,824,000, and $20,557,000 in 1996, 1995 and 1994, respectively.

NOTE I: SHAREHOLDERS' EQUITY

     On January 12, 1996, the Board of Directors of the company approved the
extension of the benefits afforded by the company's existing rights plan by
adopting a new shareholder rights plan. The new plan, like the existing plan, is
intended to promote continuity and stability, deter coercive or partial offers
which will not provide fair value to all shareholders and enhance the Board's
ability to represent all shareholders and thereby maximize shareholder value.

     Pursuant to the new Rights Agreement, dated as of January 12, 1996, by and
between the company and Norwest Bank Minnesota, National Association, as Rights
Agent, one Right was issued on March 4, 1996 for each outstanding share of
Common Stock, par value $5.00 per share, of the company upon the expiration of
the company's existing rights. Each of the new Rights will entitle the
registered holder to purchase from the company one one-thousandth of a share of
Series A Junior Participating Preferred Stock, without par value, at a price of
$130.00 per one one-thousandth of a share. The Rights, however, will not become
exercisable unless and until, among other things, any person acquires 15 percent
or more of the outstanding Common Stock of the company. If a person acquires 15
percent or more of the outstanding Common Stock of the company (subject to
certain conditions and exceptions more fully described in the Rights Agreement),
each Right will entitle the holder (other than the person who acquired 15
percent or more of the outstanding Common Stock) to purchase Common Stock of the
company having a market value equal to twice the exercise price of a Right. The
new Rights are redeemable under certain circumstances at $.01 per Right and will
expire, unless earlier redeemed, on March 3, 2006.
