FILTER CARTRIDGES: LOFMEM-G™, CRITICAL FILTRATION APPLICATIONS

 

LOFMEM-G FILTER CARTRIDGESLOFMEM-G Polyethersulfone (PES)  Membrane filter cartridges are designed for food and beverage, acids/bases, cosmetics, inks, fine chemicals and ultrapure water applications. LOFMEM-G filter cartridges are inherently hydrophilic and contain no added surfactants or wetting agents.  Polyethersulfone provides superior performance compared to nylon and Polyvinylidene Fluoride (PVDF) materials.

 

LOFMEM-G Ultrapure water filter cartridges are used by the microelectronics industry for final filtration of ultrapure water. The polyethersulfone membrane provides high contaminant capacity, superior flow rates and consistent removal of particles and microorganisms.  LOFMEM-G™ filter cartridges may be steamed or autoclaved for at least 5 one-hour cycles @ 135°C (275°F).

 

LOFMEM-G 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-G integrity testable design.
