Polytetafluoroethlene Membrane Cartridges (PTFE)

Polytetafluoroethlene Membrane Cartridges (PTFE) Materials of Construction Cartridges membrane is folded with PTFE membrane and diverting layers. Cartridges cover, housing and central pole are all made of PP. All parts are sealed by hot welding technology without any chemical infectant. Features and Benefits Membrane with strong hydrophobicity,being suitable for gas filter. Extensive applicability, extremely good chemical compatibility and good oxidation-resistance. Each filter core has been washed with ultra pure water. Experiencing 100% integrity test before ex-factory. Technical Parameter Filter ratings (micron): 0.1 , 0.22 , 0.45 , 0.6 , 0.8 , 1.
