Abstract
The present invention relates to a return air vent assembly for an HVAC system, and to components of, and a filter for, a return air vent assembly. In one form, the a return air vent assembly comprises a ceiling frame for fitment in an opening in a ceiling, the ceiling frame defining an assembly air inlet, a grille for the assembly air inlet which is pivotable between open and closed positions with respect to the ceiling frame, and an air box extending from and behind the ceiling frame, wherein each of the ceiling frame, grille and air box are made of a plastic material, and wherein the grille is adapted to receive a filter element behind it, and wherein the frame comprises a reinforcing cross-member extending between a pair of opposing sides thereof, and behind the closed grille and the filter. The return air vent assembly according to the present invention is light weight, adapted for ease of assembly and installation, incorporates a filter requiring less frequent cleaning and replacement, and reduces the tendency for return air to bypass the filter.
