In order to reduce power losses and noise emissions, the fan according to the invention is formed by several individual compressors (3) arranged in a row along the row of nozzles, the outlet openings of which directly join to form a common nozzle opening (7) by being connected to the common nozzle (6). The front nozzle part forming the nozzle opening can be made to swivel about an axis parallel to the nozzle opening.de608670patent1982-3204757
