Donaldson Simplifies Selection of Air Cleaners with Visual Guide

Online Chart Determines Right Air Cleaner for All Types of Applications and Environments

MINNEAPOLIS (Sept. 20, 2006) - Donaldson Company Inc. (NYSE: DCI) has launched an online air cleaner selection chart to aid customers in choosing the correct air cleaner for their vehicle. This interactive online tool considers the vast selection of Donaldson air cleaners and helps customers determine the appropriate model for their engine based on specific filtration requirements, such as dust level conditions and air flow patterns. Selecting the proper air cleaner is essential to maintain the best engine protection and maximum service life.

The four easy steps of the Donaldson air cleaner selection chart will quickly clarify the specific product needs of customers for all types of applications and environments. The specific dust environment, application type, airflow, and size or space requirements of the engine will narrow the range of suitable cleaners. The air cleaner selection chart responds to this selection criterion and suggests appropriate products for the application. The chart will display the air cleaner family and offer the option to view the model number and additional product information.

The air cleaner selection chart eliminates the confusion of selecting the right air cleaner. Additionally, the chart offers individual product photos and airflow diagrams to illustrate the operation of each model.
