Advantages of Multistage Compressors

Multistage compressors compress the gas or air in more than one stage.  The gas is progressively compressed over many stages to reach the final desired pressure.

The following are some of the advantages of multistage compressors over single stage compressors
  1. The volumetric efficiency of a multistage compressor is more as compared to a single stage compressor for the same delivery pressure. 
  2. Leakages are reduced
  3. The torque required is uniform.  Consequently, the size of the flywheel is reduced.  
  4. The cost is reduced for medium and large compressors.
  5. Lubrication is easy as the operating temperatures are lesser.
