air return
Ceiling suction grille
An air return is the vent or duct in a heating or cooling system that draws air back to be reconditioned.
While supply vents blow air into a room, air returns pull it back toward the furnace or air handler: The air return is blocked by furniture.
Also called a return vent or cold air return.
