The Astral Air line of air curtains produce downward air currents at door openings. By helping to curb the loss of heated or cooled air, building energy costs are reduced. Greater customer and employee comfort is achieved using an air curtain to help maintain more consistent temperatures in work areas, according to the manufacturer. The use of an air curtain reduces the intrusion of outside contaminants and flying insects, providing a cleaner, healthier environment. The Astral Air units are available in 10 different widths to fit door openings from 3 to 12 feet wide. Both heated and unheated models are available. Heating options include electric, steam, and hot-water units. The air curtains are manufactured utilizing 16-gauge steel, with a durable, baked-on powder-coated finish.
