TefloGas Filter Cartridges
Hydrophobic PTFE Membrane · Sterilizing Grade

TefloGas® Filter Cartridges are composed of a hydrophobic PTFE membrane and a specially designed unique thermal-resistant polypropylene core. They are characterized by a high filtration area, non-metallic ion release, and are easy to clean. Each filter is individually Integrity Tested to ensure microbiological safety.  They are highly recommended for all air and gas sterilizing grade applications in food and beverage, e.g. fermentation processes.
