List of featured suppliers of AIR GRILLES Return on Building Products Index
An air grille, return, is a panel or cover that allows air to flow freely through a ventilation system while preventing debris or large objects from entering and potentially damaging the equipment. These grilles are typically placed in areas where air is extracted, such as near air conditioning or heating units, to ensure that air is properly filtered before being circulated back into the building. The design of these grilles can vary depending on the application, but they are generally composed of a frame and a series of parallel slats or bars that allow air to pass through.
