An ideal solution to create an invisible, non-physical barrier in environments that need to keep their doors open.
An air curtain is a fan-powered device which is mounted either horizontally above, or vertically on the sides of a doorway.
The fan generates a high velocity jet of air, which results in an invisible screen of air over the doorway.
This air-barrier separates the two environments on either side of the doorway without hampering the access of pedestrians or vehicles with a physical barrier such as a door.
Various studies and tests have proven that air curtains are effective. When an efficient air curtain is well installed it will save on energy consumption. Simultaneously the air curtain ensures that the entrance area remains climate protected, comfortable and free of draughts, insects, odours, etc.
Advanced Computational Fluid Dynamics (CFD) diagrams made by Polytechnic University of Catalunya clearly show the efficiency of air curtains
Poorly designed air curtains, incorrectly selected units (less powerful) or inadequate installation will result in loss of part or even all the advantages. In some instances, the problems of draught at the entrance may became worse than not having an air curtain installed at all.
