ABSTRACT:
An air barrier device for an opening in a wall including air flow generating members arranged at opposite boundary edges of the opening on both sides of the opening and arranged to direct individual curtains of air obliquely towards each other and into the spaces separated by the wall to thereby define a closed air volume. Air flow sensing members are positioned at the opening and are operable to modify the operation of the air flow generating members in response to the detection of a net flow of air through the opening to stop the net air flow.
