Oil Removal Filter Bags - FOS Series

​FOS filter bags are designed to remove both oil and grease from aqueous based liquids. FOS filter bags feature a unique two-in-one bag construction which separates functional layers of material, thereby allowing maximum exposure time while keeping pressure drop across the material to a minimum. The specially engineered multi-layered construction includes an inner prefilter layer and a middle layer of polypropylene microfibers designed to hold 10 – 20 times their own weight (32 or 64 ounces) in oil and grease.
