Sterilization
All Duo-Fine E Series cartridges may be autoclaved for 30 minutes at 121°C (250°F) under no end load conditions.
Cartridges with 304 stainless steel core and end caps may be steamed in-line at 121°C (250°F) for up to one hour. Do not reverse flow under steam conditions, damage to the filter may occur.

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 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 represent the diameter of the largest hard spherical particle that will pass through the filter during standard test. 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 retention ratings given 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



Unit conversion: 1 bar = 100 kPa
Flow rate is for a 25.4 cm (10 in)cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP).


1Provided that the maximum differential pressure is not exceeded based on temperature limits defined above.
