Emflon* PFR Filter Cartridges
Validated sterilizing filtration for air and gas applications, providing protection against microbiological and particulate contamination.
Air and Gas Filtration at a Glance
Air and gas cartridge filters provide a sterile barrier that helps remove microorganisms and particulates from gases that come into contact with products or product-contact surfaces. Reliable sterilizing filtration helps support consumer safety, product quality and process protection.
Why Is Sterilizing Air and Gas Filtration Important?
Sterilizing filtration of air and gas is widely used across food and beverage and industrial applications to help support process protection, brand protection and consumer safety.
Common applications include:
- Compressed air filtration
- Gas filtration
- Tank venting
Choosing the appropriate filtration solution is important because contamination events can contribute to production disruptions, product delays, replacement costs and unfulfilled customer expectations.
Proven Performance in Sterilizing Air and Gas Filtration
What Are the Critical Attributes of Air and Gas Cartridge Filters?
Tested and Validated for Microbial Retention
Microbial validation is the most sensitive validation method of sterile air cartridge filters. Claims of expected microbial removal performance should not be based on filter media pore size rating.
Hydrophobicity
PTFE filters selected for air filtration must be highly hydrophobic to effectively remove microorganisms in both liquid and aerosol bacterial challenge solutions.
Robustness
Subject to repeated in-situ steam sterilization heating and cooling cycles during operation, it's essential that they have an extremely robust design.
Why Choose Emflon* PFR Filters?
Pall's Emflon family of validated PTFE filters meets industry demand for the highest level of sterility assurance.
Emflon membrane filters fulfill a microbial liquid bacteria challenge validation that meets requirements to remove at ≥10⁷ cfu/cm² effective filtration area according to ASTM Method 838-05, providing sterile effluent according to FDA Guidelines (2004).
Pall Emflon sterilizing-grade membrane air filters are available in multiple configurations and sizes to support a wide range of application requirements.
Emflon* PFR membrane filters provide validated sterilizing filtration for air and gas applications.
