Air curtains, also known as air doors, are devices used in commercial and industrial buildings to create a barrier of air across an opening, typically a doorway or entrance. These curtains work by blowing a controlled stream of air downward or horizontally to separate two different environments, usually an indoor space and the outdoor environment. Here are some key features and uses of air curtains

Air curtains generate a continuous flow of air that can range from a gentle breeze to a high-velocity stream, depending on the specific application and the desired effect.

Air Temperature Control

Depending on the model, air curtains can be heated or unheated. Heated air curtains are used in cold climates to create a warm barrier that prevents the infiltration of cold outdoor air.
