FIELD: engines and pumps.
SUBSTANCE: casing for channeling the air flow from the centrifugal fan of the air-cooled scroll compressor is formed by a helix with an exhaust opening and an exhaust bend connected to it in an interior angle so that the interior angle is an acute angle extending from one side of the median plane defined by the intake opening axis (X-X') and the exhaust bend center to the other side of the median plane located on the side of the transverse wall end point and at a distance (A) from said median plane.
EFFECT: increase of efficiency.
