ABSTRACT:
A replaceable filter element is installed in a filter assembly including a filter housing. There is a substantially annular space between the filter element and the housing and an air inlet for introducing inlet air tangentially with respect to the annular space. The filter element employed has a closed top and an open bottom communicating with a hollow core. An annular filter media is included in the filter element, the filter media having a top end and a bottom end with an outwardly projecting flange at the bottom end. The outwardly projecting flange has an annular rib thereon, spaced from the filter media, to define a trough between the annular rib and the filter media for retaining debris thereon. When the filter element is removed for replacement, debris accumulated on the flange is retained in the trough.
