Boltic 36" Stainless Steel Air Curtain with Plunger Door Switch

Reducing the infiltration of outside air saves you money in climate-controlled areas. Whether your internal temperature needs to stay warm and heated or the AC needs to be kept inside, this air curtain is a great solution for entry points exposed to outdoor elements, retaining internal room temperatures when external doors are open. For added convenience, the plunger door switch automatically turns the fan on and off when the door opens and closes.
