The rotary compressors are broadly classified into two main types:
1. Positive displacement type compressors:
These compressors are of single stage blowers can produce pressure upto 2.5 bar with handling capacity ranging from 0.5 m
3
/min to 1500 m
3
/min. Root blower, vane type blower and screw compressor are the examples of positive displacement type compressors.
2. Steady flow compressors:
These compressors an produce pressure upto 4:1 per impeller and with number of impellers, the pressure ratio increases. Radial or centrifugal compressor and axial compressor are the examples of steady flow compressors.
