Different accuracy levels of different filter structure,a new 'matrix blended fiber' media, larger effective surface area, improves capurerate, enhanced filtering effect. Coated closed cell foam sleeve with resists chemical attack from oils and acids, ensures high efficiencies by preventing reentrainment of coalesced liquids.Advantages:1.Duarbility and longevity2.Beautiful design...
