Radial Blower

The invention relates to a radial blower, with at least one axial air inlet port (1) and with a radial air outlet port (2), consisting of a housing subassembly and of a fan subassembly which comprises an electric motor (3) and a fan wheel (4), the housing subassembly having at least one holding part (5), which is arranged in the region of the axial air inlet port (1) and serves for the supporting reception of a carrying part (6) of a fan subassembly, and two shell parts (71, 72) which are connectable releasably to one another and divide the air inlet port (1) and between which the holding part (5) is fastened in the assembly state. In order to improve the mass/power ratio of a blower of this type, it is proposed that the electric motor (3) of the fan subassembly be an electronically commutated direct current motor. In this case, it is especially advantageous if control electronics (19) are arranged in a terminal box (13) for the reception of motor connections (12), which terminal box is fastened, in particular, to the underside of a lower shell part (72) of the housing subassembly.
