ABSTRACT:
An improved rotor for a side-channel compressor in which the ratio of the pressure of the compressor at zero output and the suction pressure of the compressor is greater than or equal to 1.79 and which rotor includes a plurality of spaced-apart blades having cells interposed therebetween. The improvement of the invention comprises the blades having a thickness dimension chosen so that the ratio of the blade cell volume to the sum of the blade cell volume and the blade volume is a maximum value of 0.72 and a minimum value of 0.45/(p.sub.max /p.sub.1 -1).sup.2.
