731 Hydraulic Products All Things Industrial Use the charts below to select filter media designed to obtain the fluid cleanliness level desired for the hydraulic or lube system being considered. Generally, the desired fluid cleanliness level is based on the types of components used in a given system. Table 1 outlines the major components affected by fluid contamination. When selecting a filter or filters for a system, make a list of the system's components and note the associated ISO cleanliness codes from Table 1 below. Example Machine: Stacker Pump: Pressure Compensated Piston - 17/15/12 / Media No. 2 1/2 Valves: Proportional Controls - 16/14/12 / Media No. 2 Actuators: Cylinders & Disc Valve Motors - 20/18/15 & 19/18/13 / Media No. 2 1/2 Select the lowest ISO code from the list as the desired fluid cleanliness level. Desired fluid cleanliness level: 16/14/12. Select the associated filter media to be used in all filter housings. Use filter media No. 2.
