Abstract (en)
[origin: WO9215789A1] The invention concerns a radial-flow fan (1) with a rotor (11), a drive motor (13), a rotor shaft (12) and lubricated shaft bearings (14, 15). The drive motor (13) and shaft bearings (14, 15) are housed in a casing (3) which has a duct (19) through which the shaft passes as well as a connection point (21, 22) through which the interior (18) of the housing can be evacuated. In order in particular to extend the lifetime of such a fan, the invention proposes that the bearings (14, 15) are designed as ceramic bearings.
