Clean, dry oil is essential for your equipment. Donaldson Company, a leader in filtration for over 90 years, has proven performance in thousands of applications – offering the industry's largest selection of replacement hydraulic, lube and gear oil filtration products for contamination control. Distributed by: Hydraulic Filter Housing Selection Guide Locate the Donaldson model closest to the intersection of the maximum operating pressure and maximum flow rate. If there is not a model at the exact intersection, select the nearest series to the right or above the intersection to ensure a filter that is adequate to handle the maximum operating pressure and flow rate has been selected. Pressure families are color coded in the selection chart for low, medium and high model series. Filter housing styles are identified by their shape.

It is important to remember that protecting and maintaining the most sensitive components within a circuit will result in effective contamination control. With the broad range of housing styles and filters available from Donaldson, how do you choose the right filter to reliably protect your systems and equipment? Follow these recommended steps to identify the correct Donaldson filter and parts required for efficient contamination control. the system operating 1 Determine pressure and flow rate Start by identifying two key factors in the hydraulic system operating environment for the most critical component being protected, such as pumps and motors. • nominal and maximum operating pressure • nominal and maximum flow rate 2 Select the filter housing model Refer to
