A device for separating adjoining spaces by air technology comprises means for generating and maintaining an air curtain at least at the position of a passage opening. These means comprise a blower device (20,40) placed on a first side of the passage opening and having blowing means extending at least substantially over a full height of a side of the passage opening. The blower device is in open communication with air displacing means (65) which impart an air stream thereto under overpressure. The blowing means comprise according to the invention a series of longitudinally successive blower units (21..23,41..43), each provided with a controllable air slit (24) from which the air stream exits during operation. In addition, the blower units are laterally orientable about a pivot axis (24). On an opposite side the system comprises a suction device (30,50) for the purpose of drawing in and recirculating the air stream received in the form of an air curtain from the blower device. |
