Air Curtain

The air curtain is mounted on the wall above the opening of the drive thru window. 
The fan blows a soft, quiet "barrier" of air downwards and is designed to keep the interior and exterior environments separated when the drive thru window is open. This separation reduces the infiltration of unconditioned cold or hot air and fumes and the ingestion of insects from the exterior. It helps to insulate servers from the elements and preserves the clean, ambient environment of the kitchen. Thus, saving energy.
