Abstract

Fan, especially designed to perform the extraction or forced introduction of air in any premises and enclosures, characterized by comprising a impeller constituted by a series of blades equal to each other, fixed between the frustoconical peripheral zone, generator inclined with respect to the axis of the assembly of a plate that has a central circular flat area, orthogonal to this axis, and a frustoconical ring, generatrix parallel to that of the said peripheral zone, whose impeller, in an essential way, is located inside a shell that forms a circular opening, located in a plane orthogonal to the said axis, conveniently facing the opening of the referred hoop, constituting the intake mouth of the fan, and an annular duct, defined, at least in an initial zone, by two frustoconical surfaces of parallel generatrices between themselves and the generatrices of the frustoconical zones of the impeller referred to above.
