2 Marksman DFN series filter cartridge retention ratings are based on Pall’s Dynamic Efficiency test protocol. This single pass, destructive challenge test is based on ASTM F-795 test procedures for determining the performance of a filter medium. Fine test dust is used as the test contaminant for filters in the 1 to 20 micron range.Coarse test dust is used for micron ratings above 20 micron. Additional information can be obtained by contacting Pall Corporation.
