Emflon® PFA Filter Cartridges

Emflon PFA filters are a further addition to the successful Emflon filter range. The filters contain a proprietary pleated hydrophobic PTFE membrane and are designed for the removal of micro-organisms and particles from air and gases.

Emflon PFA filters:

  • Offer exceptionally high-flow rates to ensure low installation and operating costs
  • Have been validated for bacterial removal in air at an aerosol challenge level of 107 Brevundimonas diminuta ATCC 19146 per 254 mm (10 in.) length cartridge
  • Can also be steam sterilized repeatedly in situ to provide long service life

Better by Design

The heart of the filter is a PTFE membrane with exceptional flow properties. Equally important is Pall's unrivalled expertise in cartridge construction drawing on many years experience in making PTFE membrane filters. Optimized pleating configuration and membrane support, together with a wide bore cartridge core and adapter, ensure that this high-flow performance can be exploited to the fullest.

Typical Biopharmaceutical Applications

  • Large-scale fermenter air
  • Intermediate product vessel venting
  • Autoclave vacuum break
  • Biopharmaceutical instrument air
  • Air and gas service lines

Features and Benefits

  • High-flow rates and low pressure drop allow use of smaller systems, minimizing installation, filter replacement, and energy costs
  • Long steaming life offering low-cost filtration

      The steam life and service life data were determined by testing under controlled laboratory conditions up to the time indicated. Actual operating conditions may affect the filters’ long-term resistance to steam sterilization and hot air service. Filters should be qualified for each process application.
