Air Curtains
Air curtains are devices that create a barrier of air across a doorway or other opening, in order to help maintain indoor temperature and prevent the entry of airborne pollutants. Air curtains are often used in commercial and industrial settings to help maintain comfortable indoor temperatures and reduce energy costs by reducing the amount of air exchange between indoor and outdoor environments.
