Description of the the PTFE pleated filter cartridge
The hydrophilic PTFE air filter cartridge is constructed of PTFE membrane media and PP support layers. All construction process is thermally welded without using any glue or adhesives to get low extraction level.Because of its large flux, high temperature resistance, resistance to acid, alkali and other characteristics, it has wide chemical applicability, and suit for fermenters, carbon dioxide, nitrogen, compressed air. For gas filtration, it can reach 100% to retain more than 0.02um various phages, bacteria and particles.
Features of the PTFE pleated filter cartridge
1.Membrane with strong hydrophobicity,being suitable for gas filter
2.Extensive applicability, extremely good chemical compatibility and good oxidation-resistance
3.Each filter core has been washed with ultra pure water
4.Experiencing 100% integrity test before ex-factory
Application of the PTFE filter cartridge
1)Sterile venting of tanks
2)Autoclave vacuum break lines
3)Fermentation air applications
4)Sterile process gases
5)CIP at ambient temperature
