Abstract

1339690 Centrifugal fans SIEMENS A G 23 June 1972 [26 June 1971] 29666/72 Heading F1C [Also in Division F4] A radial flow fan comprises a rotor 9, air guide parts 7, 8 and an electric motor 15. These parts are slidably mounted in slots 6, 6' in a housing 2, and when assembled the guides 7, 8 constitute a shrouding for the rotor 9, and are connected together by clips (10). In operation the fan draws air through apertures 17 into both ends of the rotor 9, and out through an outlet 5. The housing 2 is preferably of sound-absorbing material, such as rigid foam plastics material.
