Duo-Fine 1401 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. Contact Pall for a complete description of Pall’s test procedures.

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