Emflon® PFRW Compressed Air Filter Cartridges, Junior Style

Emflon PFRW junior style sterile compressed air filter cartridges are sterilizing grade hydrophobic membrane filters designed to provide reliable retention of bacteria and bacteriophages in compressed gas and vent applications. They are suited to handle small gas flow rates in compact installations.

The Pall Emflon PFRW filter family has been expanded to include small configurations to address the full range of gas filtration needs of the food and beverage industry. These sterile compressed gas filter elements feature Pall’s advanced 0.2 micron polytetrafluoroethylene (PTFE) double-layer membranes, pleated with high area into single open-end cartridges. They are built to withstand adverse in-situ steaming conditions in either the forward or reverse direction.

Even in the presence of high humidity or moisture, often the case in practice, Emflon PFRW cartridges provide sterile effluent and validated performance, ensuring process security. They are the cartridge of choice for small flow critical sterile gas applications.

 
Features Benefits
Strongly hydrophobic 100% PTFE membranes Prevents wetting out in humid conditions, even after repeated use and steaming cycles, allowing for unimpeded gas throughput
High area pleated, robust double-layer membranes High throughputs and low pressure drops, resulting in compact footprint and long life
Excellent resistance to mechanical damage
Multi-cycle in situ steam challenged Enhanced steaming resistance
0.2 micron sterilizing grade filters based on liquid bacteria removal Provides sterile effluent even in humid conditions, resulting in optimal protection of product, improved fermentation yields, and increased security in aseptic processes
Water Intrusion Testable (WIT) Simplifies in situ integrity testing
100% integrity tested prior to dispatch Documented quality
Individually serialized modules Full traceability to materials and production records

Performance

Removal Performance

Emflon PFRW filters have a microbial removal rating of 0.2 micron in liquids and a particulate removal rating of 0.003 micron in dry gases.
  • Tested with Brevundimonas diminuta liquid challenge at ≥107 cfu/cm2 effective filtration area, according to ASTM Method 838-05. Provides sterile effluent according to FDA Guidelines (2004)
  • Tested in accordance with ISO 8573-4 and test method ISO 12500-3:20096.
Pall has an excellent history of use of the Emflon PTFE membrane used in the Emflon PFRW filters, see ‘Validation Guide for Pall Emflon PFR Filter Cartridges’, USTR2114 (2) demonstrating:
  • MS-2 and PP7 bacteriophage aerosol challenge
  • Airborne sodium chloride aerosol challenge
  • Brevundimonas diminuta aerosol challenge in forward and reverse direction and under long term challenge conditions in forward direction with humidified air
  • Bacillus subtilis var niger spores aerosol challenge
