Gas filter KPF series

for airmembranesterilization

Product Overview
KPF sterile air and gas filters employ pleated, reinforced polyvinylidene fluoride (PVDF) microporous membrane elements for precision filtration of compressed air, process gases and compatible liquids. Elements are hydrophobic, offer broad chemical compatibility and withstand repeated steam-sterilization cycles.

Typical Applications

• Pharmaceutical processing
• Biotechnology
• Brewing
• Sterile tank venting
• High-temperature liquid filtration
• Solvent filtration
