Emflon® PFR Filters

High-Strength, Long-Life, Sterilizing-Grade Filter Membrane Ideal for Air, Gas, and Vent Filtration in Biotech Applications

Emflon® PFR sterilizing-grade membrane filters are ideal for a wide range of air, gas, and vent sterilizing filtration applications within the pharmaceutical and biotechnology industries, including:

  • Product-contact gases, such as nitrogen blanketing
  • Inlet gas and vents on bioreactors and fermenters
  • Venting of hold tanks and mixers
  • Compressed gas for instrumentation and lyophilization
  • Gas used for drying and transfer fill lines
  • Blow-fill-seal equipment
  • Environmental air in isolators

The double-layer polytetrafluoroethylene (PTFE) membrane is inherently hydrophobic, chemically inert and designed for the complete removal of contaminating bacteria and a high-titer-reduction of some viruses.


Superior Performance

Emflon PFR membrane filters meet the ever-increasing demand for air filters and offer great strength and long life, even during continuous use in hot air up to 60 °C, in vent applications up to 80 °C, and during repeated steaming in either the forward or reverse direction.

Combined with high flow rates and excellent de-wetting characteristics, Emflon PFR membrane delivers very economical filtration through smaller installations and reduced energy costs. In addition, the filters can be tested in-situ by the Forward Flow integrity test or a Water Intrusion test. Both tests are correlated to the liquid bacterial challenge test. 

Benefits

  • Rapid qualification and regulatory filing (comprehensive validation guide available)
  • Reduced installation and running costs, as high flow rates and low pressure-drops allow more compact systems to be utilized
  • Assurance of integrity and reliability due to robust design and proven performance over many years
  • Minimized changeout frequency as long steam life and long service combine to offer low-cost filtration

Consistency and Reliability of Performance

Pall manufactures the PTFE membrane used in its Emflon PFR air and vent filter capsules and cartridges, ensuring security of supply and assuring full control of membrane manufacture.

Scientifically Validated

Emflon PFR filters have been extensively scientifically validated using the most advanced methods and most sensitive equipment available. With an absolute removal rating of 0.2 µm in liquids and 0.003 µm in gases, they are validated by:

  • Brevundimonas (Pseudomonas) diminuta (ATCC 19146) liquid challenge at 107/cm2
  • Brevundimonas (Pseudomonas) diminuta (ATCC 19146) aerosol challenge
  • Bacteriophage retention (PP7/ATCC 15692-B4) aerosol challenge
  • Bacteriophage retention (MS-2/ATCC 15597-B1) aerosol challenge
  • Spore retention Bacillus atropeaus NCTC 10073, ATCC 10073, aerosol challenge
  • Airborne sodium chloride aerosol challenge
