Abstract (en)
[origin: EP2921712A1] A rotor (2) for a radial fan (1) comprises a plurality of main blades (25) positioned in sequence around a rotation axis (A) and a hub element (36) forming a guide surface (51) from which the main blades (25) project, wherein the guide surface (51) is a rotational surface with respect to the rotational axis (A) with a generatrix forming a convex radially inner portion (52), a concave intermediate portion (53), and, possibly, a substantially rectilinear radially outer portion (54) forming an outer ring that is planar and orthogonal to the rotational axis A.
