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.
Polypropylene membrane absolute rated filter cartridges are the preferred choice for general water filtration, as a DI water prefilter/postfilter and for use in aqueousbased chemical processing.
