PFG Filter Cartridge are inherently hydrophobic PTFE membranes and thick heat-resistant polypropylene core. They are characteriized with non-metallic ion release, no dead corner, easy to clean when compared with those with a stainless steel core. As a result, they are highly recommended for the sterile filtration of gas, air in pharmaceutical, biological liquids and fermentation industries.

Features and Benefits
Inherently hydrophobic
Exceptionally high flow rates with low pressure drop
Steam sterilization up to 150cycles at 121℃,30min
100% integrity test by all methods including water intrusion test
Absolute rated filter

Typical Applications
Biological fermentation
Tank vent
