OilSEP is a special adsorption type filter bag, which is designed to adsorb trace oil from liquids. It is made of PS melt-blown polypropylene filter media with internal and external protection layer. The filter media is made of superfine fibers, which form depth adsorption space. OilSEP can adsorb oil 23 times more weight than its own weight. OilSEP's excellent depth space also delivers better precision filtration performance than EcoSEP. Filter area is 0.1 m2, 0.25 m2 and 0.5 m2. Optional filter media is PS.
