The REV air curtain is designed specifically for revolving door applications to provide additional levels of environmental separation. The REV features a customizable nozzle that can fit the diameter of most revolving doors. The nozzle attaches to an air curtain that operates in the header area above the revolving door and the entire unit remains out of sight while providing all of the benefits of an air curtain. The REV is available with several heating options and can serve as a source of supplemental heat in lobby areas. The custom design of each unit ensures that it can blend seamlessly into a building’s aesthetics while creating an effective barrier to block insects, dust, exhaust and outside air from entering.
