Grade 5 Filter: High Efficiency Oil Removal. Designed for coalescing fine water and oil aerosols, this filter removes solid particulate to 0.01 microns with a 0.008 ppm w/w maximum remaining oil content (established in accordance with CAGI standard ADF400 and is based on 100°F inlet temperature). The first stage of filtration uses multiple layers of fiber media and screen to remove larger particles, pre-filtering the air, while the second stage utilizes multiple layers of bonded, blended fiber media for fine coalescence. Features Withstands temperatures to 150°F (66°C) Push-on elements provide simple replacement Piston type seals keeps unfiltered air from bypassing element Stainless steel, corrosion resistant inner and outer core> Low resistance to flow> Seam welded durability Matrix blended fiber media> Large, effective surface area ensures high efficiencies and minimizes pressure drop Coated, closed cell foam sleeve> Resists chemical attack from oils and acids> Ensures high efficiencies by preventing re-entrainment of coalesced liquids Chemically resistant end caps Silicone free Specs Model Size 20 Filter Element Grade 5: High Efficiency Oil Removal Model E5-20 Stainless Steel Element NO Flow Rating 60 SCFM Design Temp 150°F Weight 0.4 lbs
