Manufactured in polypropylene or cellulose media, the high-efficiency pleated filter cartridges provide high surface filtration and longer service life. For use with CFLV and MFLV cartridge adapter kits, the cartridges are said to be ideal for multiple liquid-purification requirements. The pleated media reportedly provides excellent particulate removal as well as low pressure drops. The greater surface area prolongs service life due to higher flow and particulate holding capacity. Available micron ratings are nominal 1, 5, 10 and 30, in 10-, 16-, 20- and 30-in. lengths. All cartridges feature DOE Plastisol PVC end caps for maximum sealing capability.
