An air curtain releases warm air from bottom to top keeping the temperatures of your restaurant in control. It eliminates the exchange of warm and cold air, hence, preventing draft. During the summer season, it promotes cool air in your business building, and keeps hot air out, maintaining a comfortable environment.
An air curtain uses a fan to force a curtain of air in a downward direction. The forced air creates an invisible barrier that helps to control temperatures by preventing hot or cold air from entering a doorway or building at an opening.
