FILTER CARTRIDGES: LOFMEM-W™, ABSOLUTE FILTRATION

 

LOFMEM-W FILTER CARTRIDGESLOFMEM-W Polyethersulfone (PES) membrane filter cartridges are made from FDA listed (U.S. CFR, Title 21) materials of construction for food and beverage contact. LOFMEM-W filter cartridges are an all-thermal bonded construction having no adhesives, non-fiber releasing nor wetting agents.

 

LOFMEM-W™ PTFE filter cartridges are compatible with most common chemical cleaning, sanitizing and sterilizing agents within a pH range of 1 to 4.

 

LOFMEM-W™ filter cartridges offer precision filtration performance in the most aggressive environments.  They are manufactured from polytetrafluoroethylene (PTFE) membrane with additional polypropylene support layers and components.  The HIMA retentive PTFE membrane offers superior hydrophobicity and water intrusion resistance compared to PVDF based media and are more economical than alternative  fluorocarbon filter cartridges.

 

LOFMEM-W filter cartridges are highly compatible with the most rigorous sanitizing methods in the beverage industry, are manufactured in ISO Class 7 cleanroom and 100% flushed. Reliability is further assured with the LOFMEM-W integrity testable design.
