Abstract:

A spin-on element includes a cylindrical housing, a tap plate at one end of the housing, and an adapter ring supported by and bounding the other end of the housing. A collection bowl can be threadably attached to the adapter ring. An imperforate inner support tube in the housing fluidly separates a central opening in the tap plate from peripheral openings. The inner tube has an inner surface defining a central chamber in fluid communication with the central opening. A perforated outer support tube surrounds the inner support tube, and has an outer surface defining a peripheral chamber in the housing. The inner and outer support tubes together define an intermediate chamber, in fluid communication with the peripheral openings in the tap plate. A nylon water coalescing mesh surrounds the outer support tube, and is curled over the ends of the outer tube. A first end cap comprising a foam gasket with openings to allow fluid to enter the intermediate chamber is disposed at one end of the support tubes.
