Abstract
The invention concerns a centrifugal fan of simple construction. The rotor consists of annular hub wheels 11 and 12, wherein a rotor tube 13 of circular cross section is fixed using shrink-fit connections so that the rotor can be installed within the convex interior of the fan. Several fans coupled in series can form a compressor. <IMAGE>
