Abstract
A filter assembly of the Vee-panel type comprising a filter frame and a plurality of complementary pairs of replaceable filter panels slidably disposed within the frame and defining a plurality of adjacent Vee's with the apexes of the Vee's being disposed adjacent the air outlet end of the assembly. The filter frame defines a plurality of rectangular perimeter panel retention surfaces thereon adjacent the sides of the filter panels for retaining the panels in place and forming an air tight perimeter seal therewith. A compressible gasket is disposed about each of the panel retention surfaces. An elongated cam surface is defined on at least one of the panels in each of the pairs of panels adjacent the air outlet end of the assembly such that upon sliding a panel into the frame such that the cam surface carried thereby is disposed adjacent the air outlet end of the assembly and then sliding the complementary panel into the frame, the complementary panel abuts and passes over the cam surface, forcing the panels outwardly apart against the adjacent panel retention surfaces and compressing the gasket therebetween. Locking clips are provided on said panels at the air inlet end of the assembly for releasably holding the panels in sealing engagement with the adjacent panel retention surfaces of the frame so as to form and maintain a perimeter compression face seal about and between each of the panels and the adjacent pane retention surfaces.
