Uses[edit]

Air doors are often used where doors are required to stay open for operational purposes, such as at loading docks and vehicle entrances. They can be used to help keep flying insects out by creating forceful turbulence, or help keep out outside air, thus reducing infiltration through the opening. Cold drafts can be avoided by mixing in warm air heated by the air door. Heated air doors are commonly used when supplemental heat is needed for a space, and to reduce the wind chill factor inside the opening, in colder climates.

Further applications include customer entryways, airplane hangars, cargo doors, drive through windows, restaurant doors, or shipping receiving doors. Non-heated air curtains are often used in conjunction with cold storage and refrigerated rooms.

Air doors can be equipped with or without heaters to heat the air. The fan must be powerful enough to generate a jet of air that can reach the floor. There are some studies in the scientific literature that present analytical methods to predict the sealing efficiency obtained with an air curtain.[2]
