PolyVENT and Sterivent Intregal Filters

The filters are integral venting filters that work bidirectionally to prevent contaminants from entering vessels like fermentation tanks during draining or filling.

The filters, venting filters with an integral PTFE membrane, are well suited for sterile venting of vessels and tanks during draining and filling
Hydrophobic 0.2 μm PTFE membrane makes it a high-quality PTFE air filter
Can be autoclaved 50 times without loss of performance; compatible with ethylene oxide (EtO)
Integrity can be tested with the water breakthrough (WBT) test
Range from 16-2000 cm² of filtration area to support even large process tanks

0.2 μm hydrophobic PTFE air filters are ideal industrial air filter media
Validated for 50 steam autoclave cycles; compatible with ethylene oxide (EtO)
Testable by water break through (WBT) test or bubble point testing
Passes USP Class VI biosafety tests for plastics
Manufactured in clean room facilities
Range of filtration areas from 4-1000 cm² to support filtration volumes as small as one liter and as large as a large tank vessel
Can be autoclaved 50 times without loss of performance; compatible with ethylene oxide (EtO)
Integrity can be tested with the water break through (WBT) test
Range from 16-2000 cm2 of filtration area to support even large process tanks
