Abstract: A radial-blade double-inlet fan (1) which includes a casing (2) with two inlet openings (8,10) facing each other, an external electrical rotor motor (14) located in casing (2), having a stator (16) and a rotor (18), and of a radial impeller (20) which is connected to rotor (18) and which axially extends on both sides beyond motor (14) into the direction of inlet openings (8,10). To absorb the oscillations, motor (14) is flexibly supported by the casing. Stator (16) is connected to stator flange (32), and rotor (18) encloses stator (16) only along one side approximately up to stator flange (32).
