ePTFE Membrane Cartridge Filters
PF-PT Series cartridges are manufactured using a highly hydrophobic ePTFE membrane. The enhanced ePTFE membrane offers exceptionally high gas flow rates at low pressure differentials (see graph). These cartridges are recommended for sterile gas filtration and venting applications. The hydrophobic characteristics of the ePTFE membrane make PF-PT Series filter cartridges particularly suitable for wet gas sterilizing applications, such as fermenter air feed.
For solvent and aggressive chemical filtration applications, PF-PT Series cartridges offer a wide range of chemical compatibility with high thermal stability. These cartridges are suitable for the most demanding microfiltration applications and can be used for the filtration of aggressive chemical solutions, including acids, alkalis, solvents, and etchants.
