Pall’s vent filters are self-contained, compact filter devices designed to provide high efficiency removal of airborne bacteria and particulate under dry and moist conditions to protect equipment, research results and laboratory environments.

GORE Microfiltration Media products incorporate a proprietary expanded polytetrafluoroethylene (ePTFE) membrane that is resistant to high temperatures and a broad range of chemicals. The unique structure of the membrane consists of billions of continuous, interconnected fibrils and nodes.

The filters in this type of system are cartridges that can be a 5-micron depth or pleated pre-filter to a final filter that is a 0.03-micron membrane filter. In a 350 GPM high purity water system the first filters would be the pre-RO filters. These filters typically have a 2.5” depth and either a string wound or a melt blown.

HIGH FLOW TETPOR II cartridges have been fully validated as 0.2 micron sterilizing grade filter cartridges, for compressed air and gas applications. They exceed liquid bacterial challenge levels as recommended by ASTM+. In addition, HIGH FLOW TETPOR II is also validated by aerosol bacterial and MS-2 Coliphage challenge testing.

5 Service life in intermittent air flow service, i.e., venting, may be significantly longer, depending on cumulative time in flowing air and temperature. 6 Values are for one 254 mm (10 in.) filter cartridge and one 127 mm (5 in.) filter cartridge. 7 Values are for one 254 mm (10 in.) cartridge and one 127 mm (5 in.) cartridge at 20 °C (68 °F

Hydrophobic PTFE filter medium provides exceptionally high air flow rates at low differential pressures Naturally Hydrophobic Membrane also provides high assurance of filter integrity and long life, during high temperature venting application and during repeated steaming.
