Abstract
The replaceable, outside-in flow filter element with integral annular trap provides a simple, efficient, tubular filter element that combines the advantages of inside out-flow and outside-in flow filters. The element includes end caps with pleated filter media extending there between. A solid tube is secured between the end caps in a position spaced radially outward from the media. The annular space between the media and the tube forms an integral, lateral, outer trap for containing filtered out particulate matter. The trap allows the particulate to be removed with the used filter element during conventional replacement. The inlet end cap includes openings spaced from an end of the filter media whereby a portion of the openings overlap the media in plan view such that inflow through this overlapping portion of the openings will flow radial outward in the space between the openings and the filter media to the annular space.
