LOFMEM T
LOFMEM T membrane filter cartridges offer precision filtration – even under harsh, corrosive environments. The polytetrafluoroethylene (PTFE) membrane with additional polypropylene support layers and components offer superior hydrophobicity and water intrusion resistance compared to PVDF based media and are more economical than all fluorocarbon filters.
Absolute rated PTFE membrane filter cartridges are suitable for gas/vent applications and the filtration of aggressive compounds. Specific uses include: strong acids and bases, compressed gases, photoresists, pharmaceutical intermediates, hot DI water and fermentation air.
