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. A second end cap with a central opening supports the other ends of the tubes and is supported on said adapter ring. A peripheral flow path is defined between the periphery of the second end cap and the housing and internally of the adapter ring, the peripheral flow path allowing fluid communication between the peripheral chamber and the central chamber. Water in the fluid coalesces on the media surrounding the outer support tube and drains down into the collection bowl.
