Abstract: A flow straightener for axial fans particularly for conditioning systems, being constituted by a plurality of flat deflection walls, which form a substantially star-shaped profile which is adapted to be arranged coaxially and proximate to the impeller of the axial fan with which it is associated.

Abstract: A wall-mounted grille particularly for the passage of air from an air-conditioning unit toward the outside, the grille being constituted by a perimetric frame inside which a plurality of deflecting vanes are fixed in a parallel arrangement and have a substantially concave transverse cross-section with the concavity directed upward, the vanes having, on their bottom, drainage openings for draining rainwater toward an underlying sloping wing which is interposed between the last lower deflecting vane and the lower edge of the frame.

Abstract: A device for moving a shutter for blocking and diverting an air stream, in climate control apparatuses, comprising a rotating element actuated by an electric motor and pivoted to a containment frame for at least part of the machine body of a climate control apparatus, a first end of a traction and pusher cable being rigidly coupled to the rotating element, its opposite end being rigidly coupled to the louver of a shutter of the louver type to be moved. The cable is arranged slidable within a sheath fixed to the frame by means of two brackets, a first one proximate to the rotating element and a second one at the opening which can be closed by the louver.
