The operating room grille is a perforated grille designed for connecting the anesthesia gas exhaust socket. It is used in the return air duct of an operating room and is installed on the wall at an accessible height or at locations where performing anesthesia may be required.
The anesthesia gas exhaust socket is mounted on this grille, and a gas exhaust pipe is connected to it. After anesthesia procedures, any residual anesthesia gas is expelled from the operating room through the return air duct to the outside environment.
