                                     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  principal  products are primarily sold through a direct sales
force.  The table below shows the  percentage of total sales  contributed by the
principal classes of similar products for each of the last three fiscal years:

                                  Year Ended July 31
                                 1994   1993     1992
                                 ----   ----     ----
    Air cleaners, filtration
      devices and accessories     67%     68%     71%
    Acoustical Products           11%     11%      9%
    Other                         22%     21%     20%

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

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


  2



SEASONALITY

    The Company's business is not considered to be seasonal.


MAJOR CUSTOMER

         Approximately  12% of the Company's 1994 sales were made to Caterpillar
Inc. and  subsidiaries  ("Caterpillar").  Caterpillar has been a customer of the
Company for many years and they  purchase  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, 1994, the backlog of orders expected to be delivered within 90
days was $111,147,000. The backlog at August 31, 1993 was $88,953,000.


COMPETITION

    Principal methods of competition are price, 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.

    Generally the Company does not provide rights to return  merchandise or give
extended  payment  terms to customers  and believes the industry  practices  are
similar to its own.


RESEARCH AND DEVELOPMENT

    During 1994 the  Company  spent  $10,873,000  on  research  and  development
activities  relating  to the  development  of new  products or  improvements  of
existing products or manufacturing  processes.  The Company spent $11,364,000 in
1993 and $10,323,000 in 1992 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.
