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.
