Air Curtains

An air curtain is a fan-powered device that is mounted either horizontally above or vertically on the sides of a doorway.

The fan generates a high-velocity jet of air, creating an invisible screen over the doorway. This air barrier separates the two environments on either side of the doorway without obstructing the access of pedestrians or vehicles with a physical barrier such as a door.

Various studies and tests have proven the effectiveness of air curtains. When an efficient air curtain is well installed, it saves on energy consumption. Simultaneously, the air curtain ensures that the entrance area remains climate-protected, comfortable, and free of draughts, insects, odours, and more.

Advanced Computational Fluid Dynamics (CFD) diagrams made by the Polytechnic University of Catalunya clearly show the efficiency of air curtains.
