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 颇尔 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 颇尔 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.
