ABSTRACT:
A housing for HEPA filters is disclosed, which includes a side access opening for receiving one or more filters, and a filter clamping assembly for seating and unseating each of the filters against its seal. The clamping assembly comprises a pair of filter clamping mechanisms extending transversely across the interior of the housing and along the top and bottom side walls, respectively. Also, a handle is pivotally mounted between the two clamping mechanisms adjacent the opening, and the handle is connected to each clamping mechanism such that rotation of the handle serves to actuate the mechanisms. In one embodiment, the handle is releasably connected to the two mechanisms, and the mechanisms are releasably mounted to the top and bottom side walls, whereby the entire assembly may be disassembled and removed from the housing through the side access opening to permit the repair or replacement of a defective component. In another embodiment, the entire clamping assembly comprises an interconnected unit, which is releasably mounted in the housing. The invention finds particular utility in the case of housings used for the cleaning of exhaust airstreams containing potentially dangerous substances, and wherein the components of the clamping assembly may be removed and replaced through the side access opening in the housing by the bag-in, bag-out procedure.
