Abstract
An air return filter grille assembly having a perforated faceplate hingedly attached to a molded fiberglass plenum. The molded fiberglass plenum has a performed recess for reclining and positioning a filter resting on the faceplate. An abutment and leaf spring on the faceplate hold the filter firmly in the recess. The air filter grille assembly is constructed to mount easily on T-bar suspended ceilings with the perforated faceplate held closed by manually rotatable pawls. Another reason for the spring is to keep the filter in position as the unit cycles on and off, thus preventing the accumulated dust and dirt on the filter from staking down or dusting back into the room.
