E1-20 Replacement Filter Element


Grade 1 Filter: Oil Vapor Removal Filter. Removes oil and hydrocarbon vapors normally adsorbed by activated carbon. Removes solid particulate to 0.01 microns with a 0.003 ppm w/w maximum remaining oil content (established in accordance with CAGI standard ADF500 and is based on 100°F inlet temperature). Designed for a 1000-hour life at the rated conditions. Multiple layers of fiber media and screen remove larger particles, pre-filtering the air in the first stage of filtration. In the second stage, multiple layers of bonded, blended fiber media is utilized for fine coalescence. Multiple layers of fine media prevent particle migration.
