PMF® Medium

Print Product Information

By employing extremely small diameter stainless steel fibers, Pall Corporation is able to produce media with absolute removal ratings that range from 2.5 micrometers to 40 micrometers in liquid service. Pall’s unique patented process uses extremely small diameter fibers, resulting in high void volume media with increased dirt capacity and long life. Pall manufactures three standard types of PMF medium:

FH Series–High pressure (up to 1000 psi) (69 bar) pleatable media.
FL Series–Low pressure (up to 250 psi) (17.24 bar) pleatable media.
FS Series–High dirt holding capacity in a profiled pore structure for polymer segment applications.

316L is the standard material of construction

¹ Liquid removal efficiency ratings are based on a modified F2 test method and actual particle count data. The 98% removal values should be used when comparing PMF grades to other competitive fiber metal media. ² These thicknesses include upstream mesh and downstream support media which is required with all PMF FS series media.
