STERIPleat Vent – Sterilising Grade Filter Cartridge for Air/Gases

The enhanced Hydrophobic PTFE membrane offers exceptionally high gas flow rates at low pressure differentials. STERIPleat Vent cartridges are recommended for sterile gas filtration and venting applications. The hydrophobic characteristics of the PTFE membrane make the STERIPleat Vent filter cartridge particularly suitable for wet gas sterilising applications, such as fermenter air feed.
