Filter cartridges

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. 

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.
