Emflon® PFRW Filter Cartridges
For Sterile Filtration of Gases

Emflon PFRW cartridges are sterilizing grade hydrophobic
membrane filters designed for reliable retention of bacteria
and high levels of phages in compressed gas and ventapplications.

Description
The filter element features Pall’s advanced 0.2 micron rated
polytetrafluoroethylene (PTFE) double-layer membranes,
pleated with very high area into single open-end cartridges.
They are built to withstand demanding in situ steaming
conditions in either the forward or reverse direction.
Even in the presence of high humidity or moisture, often thecase in practice, Emflon PFRW cartridges provide sterile
effluent and validated performance, ensuring processsecurity. They are the cartridge of choice for critical sterile
gas applications.

Features and Benefits
FeaturesBenefits

Strongly hydrophobic 100 %PTFE membranes• Prevents wetting out in humidconditions, even after repeateduse and steaming cycles, allowing
for unimpeded gas throughput

High area pleated, robust
double-layer membranes• High throughputs and low
pressure drops, with sizing
resulting in compressor energy costsavings• Excellent resistance to mechanicaldamageEmflon PFRW Filter Cartridges

Technical Information

Removal Performance

The technical information provided is based on controlled laboratory tests doneon typical production filters at the conditions described, unless otherwise
indicated. Actual operating conditions may affect the filter's performance.

Emflon PFRW filters have a microbial removal rating of 0.2 micronin liquids and a particulate removal rating of 0.003 micron in drygases.

Nominal Filter Area: 0.8 m2 (8.6 ft2) per 254 mm (10") module• Tested with Brevundimonas diminuta liquid challenge at ≥ 107
cfu/cm2 effective filtration area, according to ASTM Method 83805. Provides sterile effluent according to FDA Guidelines (2004)

Pall has an excellent history of use of the Emflon PTFE membraneused in the Emflon PFRW filters, see ‘Validation Guide for Pall
Emflon PFR Filter Cartridges’, USTR2114 (2) further demonstrating:

For continuous gas flow above 60 °C (140 °F), Emflon HTPFRW filters arerecommended. Emflon PFRW can be operated at higher temperatures for
shorter periods.

4For applications requiring autoclaving and sterlization, Pall recommends the useof Code 2 or Code 7 adaptors to ensure filter sealing after cooling. Cartridges
should be cooled to system operating temperature prior to use. Data shown forforward steam flow also indicates autoclave resistance.
