HIGH FLOW BIO-X sterile gas filters combine proven depth filter technology and a pleated construction to provide retention down to 0.1 micron in gas. They include a stainless steel inner core and are 100% integrity testable by aerosol challenge.

HIGH FLOW TETPOR II is a new generation of sterilizing gas filters setting the standard with an unrivalled combination of efficiency, flow rate and strength. They can be in-situ steam sterilized for 225 cycles and are fully validated to liquid bacterial challenge as well as aerosol and viral challenge.

HIGH FLOW TETPOR H.T. gas sterilization filter cartridges provide unrivaled performance in applications where continuous cartridge operation of up to 100 degrees Celsius (212 degrees Fahrenheit) is a requirement. These filters offer biosecurity with absolute rated filtration and a stainless steel inner core. They are steam sterilizable to 142 degrees Celsius (287 degrees Fahrenheit) and provide exceptionally high flow rates with low pressure drops.

Valairdata 4 is the next generation of fully automated aerosol challenge integrity test unit, designed to test the integrity of sterile gas filters quickly and easily.

The Valairdata 4 aerosol challenge test is fully correlated to aerosolized B. diminuta, B subtilis and Enterobacteria phage MS2 challenges and is a recommended test methodology in the PDA's "Sterilizing Filtration of Gas - Technical Report #40".

PHB Filter housings are specifically designed for use with compressed air and can be used in Industrial Fermentation for inlet air and off-gas filtration applications. PHB filter housings are available in a range of sizes to suit your process, anywhere from a single filter cartridge up to 32 x 30” filters.
