How An Air Door/Air Curtain Works
A Save-T Air Door/Air Curtain creates an invisible barrier of high velocity air to separate different environments. Air enters the unit through the intake. It is then compressed by scrolled fan housings and forced through a nozzle which is directed at the open doorway. The system utilizes centrifugal fans mounted on direct driven, dual shafted motors. The result is a uniform air screen across the opening with enough force to stop winds up to 25 mph.

Note: When there is an indraft caused by an exhaust system in the building (negative pressure), the performance of any air door will be heavily affected.

Applications
Air doors/air curtains are commonly used on both exterior and interior doorways. The following information, illustrations, and photographs will show you what an air door can do for your business.

Energy Conservation

Air doors/Air Curtains will work effectively year round and control energy costs by keeping heated and air-conditioned air in the building. In the winter, an air door will recirculate the hot air that naturally rises to the ceiling, while creating a barrier that keeps out the cold air.

In the summer, that barrier works to keep hot, humid air outside where it belongs, while maintaining a cool, comfortable environment inside. When used for energy control the average payback time (in saved energy costs) for an air door is less than two years.

Flying Insect Control Air doors/air curtains are commonly used where it is necessary to stop insects from entering a building to meet with FDA or NSF requirements. Bugs approaching the doorway will be stopped by a screen of air too powerful to penetrate.

Cold Storage For cooler doors, air doors/air curtains are the safest, most energy efficient containment devices on the market. Air doors can save hundreds of dollars of energy costs lost through open cooler doors.

Dust Containment And Humidity Control Air doors/air curtains can be used in applications where the infiltration of airborne dust particles or where high humidity levels cannot be tolerated. The invisible screen of air will allow the unrestricted passage of equipment and personnel while preventing dust or humid air from coming in. This principle holds true for almost any airborne contaminate or nuisance.
