<p>A ventilation grille for air intakes, comprising a circular or polygonal annular body (11) that is internally monolithic with a plurality of parallel and spaced vanes (12), and at least one stiffening element (13) arranged transversely to the vanes (12). A perimetric seat (14) is formed in the annular body (11) and is adapted to accommodate a supporting frame (17) for a device (18) for internal elastic anchoring to an air intake or elements (25, 26, 27) for coupling to the intake of a ventilation duct. <IMAGE></p> |
