Pre-Filters are rated for 5 Micron Particle Removal Efficiency and 5 PPM Oil Removal Efficiency.
P series filters remove bulk contaminants and protect higher efficiency filters downstream. Pre-filters allow downstream higher efficiency filters and devices to perform better and for a longer period.
Pre-Filter Elements feature an Outside to Inside flow pattern, wrapped / depth micro-glass media layers around a strong helix inner tube and easy to remove access handles.
Element changes are recommended at 10 PSI Pressure drop or at least once per year. Keeping spare elements on hand is always advised.
