Emflon® PFR Junior Style Filter Cartridges

Emflon® PFR filters have been developed from the successful Emflon filter range launched in 1981 and widely used as air and gas-sterilizing filters in the pharmaceutical and biotechnology industries. The Pall PTFE membrane is inherently hydrophobic, chemically inert and designed specifically for removal of contaminating bacteria and viruses. Emflon PFR filters meet the ever-increasing demand for air filters with greater strength, longer life and the ability to withstand the rigors of in situ steaming in the forward or reverse direction.

Superior Performance

Emflon PFR filters provide high assurance of filter integrity and long-life, even during continuous use in hot air up to 60 °C and after repeat steamings for a typical period of up to 12 months.   This is combined with high flow-rates and excellent de-wetting characteristics resulting in very economical filtration through the use of smaller installations and reduced energy costs. In addition, the filters can be tested in situ by the Forward Flow integrity test or by a Water Intrusion test. Both tests are correlated to liquid bacterial challenge — the ‘worst case’ challenge.

Scientific Validation

Emflon PFR filters have been extensively and scientifically validated using the most advanced methods and the most sensitive equipment available. They have a microbial removal rating of
0.2 µm in liquids and a particulate removal rating of 0.003 µm in gases and have been
validated by:

  • Brevundimonas diminuta liquid challenge at 107/cm2
  • Brevundimonas diminuta aerosol challenge
  • PP7 and MS-2 bacteriophage aerosol challenge
  • Bacillus subtilus Var niger spores aerosol challenge
  • Airborne sodium chloride aerosol challenge at 100 L/min flow giving a 0.003 µm rating in gases
