Abstract: Disclosed are pleated paper barrier type air filter elements having planar filter panels that are cleaned by a reverse air jet cleaning system which includes one or more specifically shaped cleaning air manifolds or heads in which a plurality of jet nozzles or orifices are arranged in a predetermined pattern to provide a totally enveloping air jet which is discharged into a flow tube immediately downstream of the clean air flow chamber of a generally tubular filter element. The jet pattern provides a temporary pressure seal within the flow tube and entrains a substantial amount of ambient air into the reverse flow jet to thoroughly flush elements to clean dust cake from the exterior surfaces thereof. The multiple jet arrangement reduces the overall space occupied by the reverse jet cleaining system and provides a larger mass flow of cleaning air. Multiple jet orifice heads or manifolds may be configured in virtually any geometric shape to provide a desired jet pattern. The planar filter panel elements allow high media face velocites with low flow tube velocities. Oval filters are provided which have a greater clean air flow area than a plurality of cylindrical elements fitted within the same dimensional envelope.

Abstract: Disclosed is an air filtration and filter mounting system. The system includes a clean air plenum having a wall with an inlet opening therein. A pair of substantially parallel tension bars are connected to and extend perpendicular to the plenum wall spaced on opposite sides of the plenum inlet. A gimbal plate is slidingly mounted on the tension bars. A filter element is positioned between the tension bars and between the gimbal plate and the plenum wall about the inlet opening. A clamping bar is fixedly connected to the tension bars outward of the gimbal plate and a screw is threadedly engaged with the clamping bar to urge the gimbal plate into clamping engagement with the filter element.
