Emflon® PFAW Filter Cartridges

For Bioburden Reduction in Dry Gases

Emflon PFAW cartridges are high capacity hydrophobic membrane filters designed for reliable reduction of particles and microorganisms in compressed gas and vent applications.

The filter element features Pall’s proprietary 0.2 micron polytetrafluoroethylene (PTFE) membrane, pleated to give high area in single open-end cartridges.

Emflon PFAW cartridges offer exceptionally high flow rates to ensure low installation, operating, and compressor energy costs. They provide an economical solution for large-scale fermenter air, general purpose venting, instrument air, and general duty air and gas service lines.

Features and Benefits

 
Features Benefits
Strongly hydrophobic 100 % PTFE membranes Prevents wetting out in humid conditions, even after repeated use and steaming cycles, allowing excellent gas throughput
High area pleated, robust membrane construction Enables extremely economical installations and compressor energy savings due to high flow rates and low pressure drops
Multi-cycle autoclave and in situ steam challenged Enhanced steaming resistance
Validated for bacteria removal in air with aerosol challenge Provides reliable and economical bioburden reduction in dry gas, protection of microbial cultures, protection of tank contents, and improved fermentation yields
Integrity testable by forward flow or pressure hold test Ensures process security
100% integrity tested prior to dispatch Lot traceable with documented quality

Steaming

 
Cumulative Steaming Time Operating Temperature
40 hours (1-hour cycles, forward) 140 °C (284 °F)
100 hours (1-hour cycles, forward) 125 °C (257 °F)
