What is an Air Door/Curtain?

An air door, also called an air curtain, employs a controlled stream of air aimed across an opening to create an air seal. This seal separates different environments, while allowing a smooth, unhindered flow of traffic and unobstructed vision through the opening.

Because air doors/air curtains help to contain heated or air conditioned air, they provide sizeable energy savings and personal comfort when applied in industrial or commercial settings. Air curtains can also be used to stop the infiltration of flying insects.

Air Curtains Cut Energy Costs, Improve Air Quality, Increase Safety

Dock & Door Air Doors/Air Curtains keep unconditioned air, fumes, and insects from entering buildings through open doorways, saving energy and creating healthy, comfortable environments. By employing the correct balance of Volume, Velocity, and Uniformity, an unheated unit has an average payback of 2 years or less. We have models designed to protect any opening, all the way up to a 30′ high dock door.

Our technology is Proven, AMCA (Air Movement & Control Association) certified performance and 100% made in the USA.
