Heavy Duty Air Curtains

An air curtain is a fan-powered device that creates an invisible air barrier over the doorway to separate efficiently two different environments, without limiting the access of the people or vehicles.The forced air produces an impenetrable barrier that serves to regulate temperature by preventing hot or cold air from entering a doorway or a structure through an aperture. Air curtains are also used to prevent insects, dust, pollen, and other waste from entering an interior space.
