Air Grill

Product Details:

A Return Air Grill, also known as a return air grille or simply a return grille, is a ventilation component commonly found in heating, ventilation, and air conditioning (HVAC) systems. Its primary function is to facilitate the return of air from a conditioned space back to the HVAC system for re-circulation and conditioning. The grille is typically installed on walls, ceilings, or ductwork openings and features a series of slats or louvers to allow air to flow while preventing the entry of larger objects.
