Abstract
A filter assembly of the Vee-panel type including a filter frame and a plurality of complementary pairs of replaceable and interchangeable filter panels slidably mounted within the frame and defining a plurality of adjacent Vees with the apexes of the Vees being disposed adjacent the air outlet end of the assembly. The filter frame defines a plurality of rectangular perimeter panel retention surfaces adjacent the sides of the filter panels for retaining the panels in place and forming an airtight perimeter seal therewith. A compressible gasket is disposed about each of the panel retention surfaces. The extended ends of each of the filter panels is provided with an end cap secured thereto. Each end cap defines a pair of identically configured cam surfaces thereon proximate the extended ends thereof. One of the cam surfaces on each of the end caps is disposed between each of the pairs of filter panels at the apex of the Vee defined thereby and abuts a cam surface on the end cap of the other panel in the pair, forcing the panes outwardly against adjacent panel retention surfaces and compressing the sealing gaskets therebetween. The other cam surface defined by each of the end caps is disposed adjacent the inlet end of the assembly and is releasably engaged by a locking clip carried by the frame at the inlet end of the assembly to form and maintain perimeter compression seals about and between each of the panels and the adjacent panel retention surfaces.
