Air curtains are motor driven devices which deliver a stream of high velocity air. They are mounted above or to the side of an opening and create a continuous curtain of air across the opening. This inhibits the penetration of unconditioned air into a conditioned space. It also inhibits insects, dust and debris from entering.
Some air curtains provide temperature controlled air. These devices may be gas fired or have air coils.
Typical applications include: food service areas%3B department stores, airports and convention center entrances%3B loading docks.
