Kleenpak™ Capsules with Emflon® PFR Membrane
Description
Pall Kleenpak™ filters combine the widest available range of filter media with specially designed self-contained
assemblies, to satisfy the very highest standards of filtration security and user convenience.
Emflon® PFR Filter Medium
At the heart of every Kleenpak Emflon PFR Capsule filter is a high-performance pleated cartridge, containing
proprietary PTFE membrane. The high-strength PTFE membrane is inherently hydrophobic, chemically inert,
and designed specifically for removal of contaminating bacteria and viruses. Emflon PFR filters have a
microbial removal rating of 0.2 µm in liquids and a particulate removal rating of 0.003 µm in gases. Emflon PFR
filters meet the ever-increasing demand for air filters with greater strength and longer life.
Clean and Robust Design
The Kleenpak filter uses well-proven proprietary Pall techniques for filter construction and heat sealing.
The highest possible security against filter bypass is ensured, even under conditions of pulsed flow
High-strength design allows multiple autoclave cycles for extended use and maximum filter economy
Polypropylene outer shell is designed to provide long-term assurance of pressure and temperature
ratings
A total absence of glues, binder resins and surfactants results in very low filter extractables and
extremely clean filtrate
High Quality Standards
Every Pall Kleenpak filter is manufactured to a very high standard of quality assurance and cleanliness, and in
accordance to a quality system accredited to ISO 9000.
For pharmaceutical use, the P designation in the part number provides full traceability supported by a certificate
of test.

Warning: Kleenpak filters must not be in situ steam sterilized by passing steam through under pressure. The figures are maximum
allowable figures determined by testing under controlled laboratory conditions to the total number of hours indicated. Actual
operating conditions may affect the filters long-term response to sterilization. Filters should be qualified for each process application.
