Duo-Fine E 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, to some extent, on 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 absolute ratings given above represent the diameter of the largest hard spherical particle that will pass through the filter under normal operating conditions. Contact Pall for a complete description of Pall's test procedures.

The DOP test measures the ability of the filter to capture fine droplets in air or gas. The retentions given above represent the removal efficiencies with respect to an aerosol dispersion of 0.3 µm Dioctyl Phthalate (DOP) particles.

Typical Flow vs. Differential Pressure for Application Sizing

Flow rate is per 10" (25.4 cm) cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP).
