LOFMEM W membrane filter cartridges use absolute rated polypropylene and polyethersulfone components that are both hydrophilic and asymmetric. Engineered specifically for economical overall filtration, they offer superior flow rates and throughputs.
LOFMEM W membrane absolute rated filter cartridges are the preferred choice for general water filtration, as a DI water prefilter/postfilter and for use in aqueous based chemical processing.
