ABSTRACT:
A spin-on filter coalescer unit having a flow reversing assembly. The filter-coalescer unit includes a cylindrical body which contains an annular filter element surrounded by a coalescing element, and a final separation stage is spaced radially outward of the coalescing element. A cover encloses the open end of the body and is provided with a central outlet port and a plurality of circumferentially spaced inlet ports. The flow reversing assembly comprises a pair of baffle members, one of which can be the cover, which are spaced apart to define a chamber that communicates with the outlet. A plurality of tubular connecting members form sealed conduits extending through the baffle member and establish communication between the inlet ports and the central axial passage within the filter element. Liquid entering the unit through the circumferentially spaced inlet ports flows through the tubular connectors and into the central passage, and then outwardly through the filter and coalescer elements and separation stage to the outer circumferential passage between the separation stage and the body, and then axially through the circumferential passage for discharge, via the chamber between the baffle members, through the outlet.
