Abstract
An inline ultra-high efficiency filter comprising a housing having a chamber extending the length thereof, an inlet and an outlet providing flow passages into and from the chamber. Seated in the chamber is a porous sintered metal filter element having a tubular body open at its end adjacent the inlet and an end wall at its other end adjacent the outlet, and the filter element provides an internal flow passage extending therein from the inlet to the end wall. A sealing weldment provides an air tight seal between the periphery of the filter element and the housing adjacent the inlet. The filter element is spaced from the wall of the chamber to provide a plenum space thereabout, and a gas stream entering the inlet end of the filter passes into the internal flow passage of the filter element and outwardly of the body of the filter element into the plenum space and thence outwardly of the outlet end of the filter. This filter achieves a 9LRV efficiency determined for the most penetrating particle size at the rated flow.
