ABSTRACT:
An end cap of a filter element has canted fins in an annular space between a filter element and filter housing for imparting a rotary motion to a fluid prior to the fluid passing through the filter element. The end cap includes a plurality of axially extending legs upstream of the fins, which legs engage a nutplate. Spaces between the legs provide an inlet allowing dirty fluid to flow to the outside surfaces of the filter element. The fins remove large particles from the fluid by centrifugal force so that large particles do not add to the contaminant load in the filter elements.
