Zusammenfassung:	PROBLEM TO BE SOLVED: To improve a cooling system and the safety of a high-speed radial fan. SOLUTION: A radial fan (1) when it includes a high-speed radial fan has a vane (8) and a casing (2). The casing (2) accommodates a rotor (6) and a stator (5) of an electric driving device (4) for a driving shaft (7)of the vane and is provided with a cooling means. The electric driving device (4) is cooled by a partial gas flow (T) separated from a main compressed gas flow (H). In the radial fan, the partial gas flow is separated, and then enters a passage of a cooling channel housing (14); and in the passage portion of the cooling channel housing, the partial gas flow is at least cooled indirectly and actively by the cooling means.
