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.
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
- 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

Cumulative Steam Life1
Steaming in Normal Flow Direction up to 140 °C @ 300 mbar Differential Pressure2,3
1 Steam life validated using 1 hour cycles.
2 Reverse steaming: Up to 125 °C @ 300 mbar maximum ∆P for 10 cycles (for filter part numbers MCY4463PFR and MCY2230PFR).
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.
