A single-stage or multi-stage centrifugal blower for hot fluids has a rotor whose housing is made of steel or carbon filaments and whose vanes are made of a ceramic material. The internal surface of the housing is shielded from hot fluids by a lining which is made of a heat-resistant and heat-insulating material and which shares the angular movements of the rotor. The housing can stand pronounced tensional and bending stresses, and the vanes and the lining are designed to stand the pressure of the conveyed and/or compressed fluid or fluids. The blower can be used as a turbine, a suction fan or a pump and can convey gases whose temperature is in excess of 1600 DEG C. and whose pressure is in the range or in excess of 2000 mm water column.
