Emflon® PFRW Kleenpak™ Capsules

For Small Scale Sterile Filtration of Gases

Pall Kleenpak capsules combine Pall’s proprietary Emflon PFRW membranes for sterilizing filtration of air and gases with specially designed self-contained assemblies, to achieve filtration security and user convenience in small scale compressed gas and vent applications.

Description

At the heart of every Kleenpak Emflon PFRW capsule are Pall’s advanced 0.2 micron rated polytetrafluoroethylene (PTFE) double-layer membranes, which provide high performance sterilization of gases. The robust PTFE membranes are inherently hydrophobic, and designed specifically for reliable removal of bacteria and bacteriophage.

These filters fulfill a microbial liquid bacteria challenge validation according to guidelines for sterilizing grade gas filters, and have a particulate removal rating of 0.003 micron in gases. They provide sterile effluent, ensuring process security.

The Kleenpak capsule uses well-proven proprietary Pall techniques for filter construction and heat sealing, to ensure highest possible security against filter bypass, even under conditions of pulsed flow. It is designed to withstand multiple autoclave cycles over the life of the filter. The capsule configuration includes a 38 mm (1.5 inch) sanitary clamp coupling connection to allow for easy installation into existing pipework.

Technical Information

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

Operating Characteristics in Compatible Gases1

 
Maximum Supply Pressure Operating Temperature
3.5 bar (50.8 psig) ≤ 40 °C (104 °F)
 
1 Air, nitrogen, or other compatible gases.

Autoclave2

 
Cumulative Autoclave Steaming Time Operating Temperature
50 hours 140 °C (284 °F)
 
2 Kleenpak filters must not be in situ steam sterilized by passing steam through under pressure, as this can result in rupture of the assembly. The figures are maximum allowable figures determined by testing under controlled laboratory conditions to the total number of hours indicated. Actual life time in use may vary.

Removal Performance

Emflon Kleenpak PFRW capsules provide sterile effluent3 when liquid challenged with Brevundimonas diminuta (ATCC 19146) microorganisms at ≥107 cfu /cm² effective filtration area.

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) further demonstrating:
  • Particulate removal rating of 0.003 micron in dry gases
  • MS-2 and PP7 bacteriophage aerosol challenge
3 Where ‘sterile air' is defined as that filtered using a 0.2 μm liquid rated filter, capable of removing 107 of Brevundimonas diminuta per cm2 of effective filtration area, in laboratory tests

Typical Flow Rates4



4 Typical clean differential pressure per capsule, air at 20 °C (68 °F). For gases other than air please contact Pall for proper sizing.
