Manufactured by NexJen Technologies, Ltd. - Waltham, Middlesex County MA

Abstract: An oil water coalescing separator has a coalescing chamber containing oil coalescing media. The separator is preferably substantially transparent so that the thickness of the band of coalesced tramp oil can be visually discerned at a glance. The separator preferably has a magnet base so the separator can be hung on a machine off the floor. The separator is also removable from the magnet base. Claim: An apparatus for separating oil from an oil water mixture, said apparatus comprising an oil water coalescing separator having a coalescing chamber having a sidewall, said coalescing chamber containing oil coalescing media, said separator containing during operation an aqueous fluid and a band of collected tramp oil having a thickness and floating on top of said aqueous fluid, said band having a bottom surface, at least a portion of said sidewall being sufficiently transparent or translucent so that the location of said bottom surface can be visually discerned through said portion by an unaided eye of an ordinary observer standing 8 feet away in ordinary lighting conditions, said separator being joined to two or more magnets effective to hold said separator during normal operation off a floor on a vertical steel surface, said separator having a back panel, said two or magnets being mounted outside said aqueous fluid and spaced apart on a backside surface of a magnet base, said magnet base being located adjacent to but distinct from said back panel, said separator being removably mounted to said magnet base by a plurality of spaced apart bolts, each said bolt including a bolt head and a latch head lip at opposite ends thereof and extending through corresponding holes in said panels and said magnet base that said bolt head engages said front panel and said latch head lip engages said backside surface of said magnet base.
