Multiplicatory centrifugal compressors for compression of air, oxygen, nitrogen and coolants find application in modern manufactures of air separation products. Advantages of compressors of new generation «Aerocom» on the basis of which three unified lines created are considered. In designs of these compressors the console arrangement of driving wheels is applied. Such compressors can be created on the basis of the minimal number of the unified elements. The basic characteristics of three lines of compressors «Aerocom» are resulted. It is informed on development of design which provides high reliability of connection of the driving wheel of the compressor with shaft.
