(54) Electrically heated fan


(57) A series of fans for hot air conveyors with rotating fan has the common characteristics to have blades (1; 16; 33) with resistive electric paths (8; 16; 34) that are electrically supplied in order to generate by themselves heat for the heating of the conveyed air. The resistive electric paths can be made of resistors (8; 34) that are applied to the blades (1; 33) or else they can be defined by the same blades (16), made of electrically conductive material.
