Air Curtains An air curtain is a device that creates an invisible barrier of high-velocity air over a doorway or entrance, effectively separating two different environments. Commonly installed in commercial and industrial settings, air curtains are used to prevent the entry of dust, insects, and pollutants while maintaining indoor temperature control. They help in reducing energy loss by minimizing the escape of conditioned air, whether heated or cooled, thereby lowering HVAC costs. Air curtains are often found in retail stores, warehouses, restaurants, and hospitals, where they improve both comfort and hygiene without obstructing physical access.
