Abstract
A filter housing assembly for exhaust applications and method of testing the same is provided. In one embodiment, the filter housing assembly includes a housing having a filter receiving aperture, a first air flow port configured to couple the housing to an exhaust system and a second air flow port sized to deliver a flow capable of providing at least 75 feet per minute of air flow through the filter receiving aperture. A filter element is sealingly disposed in the filter receiving aperture of the housing. A cap is provided that operably seals the second air flow port when not in use. In another embodiment, a method for testing a filter housing assembly for exhaust applications includes providing air through a filter element disposed in the housing in a direction opposite an operational air flow direction, leak testing the filter element from a roomside of the filter element, and, flowing air through the filter element after leak testing in the operational direction.
