Air curtains, also commonly called air doors, are used in many commercial and industrial applications. They have two key functions. One is to use an air curtain to separate one environment from the other, such as a cold storage environment from an ambient environment to minimize cold air loss. The other is to have the air door protect your inside environment from insects, dust, dirt and just about any airborne pollutant, which is key in food storage and food serving applications. Air curtains mount over your existing door opening and are triggered on and off when the door opens and closes.
