Duo-Fine P Series filter cartridges have been extensively laboratory and field tested to determine removal efficiencies in the most stringent of operating conditions.

The removal rating of any filtration device will depend on, to some extent, the conditions under which it is used or tested. The test results will be influenced by the nature of the fluid, its viscosity, the flow rate, the type of contaminant, and the temperature.

The ratings given above represent the diameter of the largest hard spherical particle that will pass through the filter during standard test. Consult Pall for a complete description of Pall's test procedures.

Typical Flow vs. Differential Pressure for Application Sizing

Typical Flow vs. Differential Pressure for Application
Flow rate is for a 25.4 cm (10 in) cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP).
