Sr. No.	Aspect	Reciprocating Compressor	Rotary Compressor
1	Pressure Ratio	Discharge Pressure of air is high. The pressure ratio per,stage will be in the order of 4 to 7.	Discharge pressure of air is low. The pressure ratio per,stage will be in the order of 3 to 5.
2	Handled Volume	Quantity of air handled is low and is limited to 50m3/s.	Large measure of air handled can be handled and it is,about 500 m3/s.
3	Speed of Compressor	Low speed of compressor.	High speed of compressor.
4	Size of compressor	Size of Compressor is bulky for given discharge volume.	Compressor size is small for given discharge volume.
5	Air supply	Air supply is intermittent.	Air supply is steady and continuous.
6	Compressed efficiency	Higher with pressure ratio more than 2.	Higher with compression ratio less than 2.
7	Maintenance	Higher due to reciprocating engine.	Lower due to less sliding parts.
8	Lubrication	Complicated lubrication system.	Simple lubrication system.
9	Initial cost	Higher	Lower
10	Suitability	For medium and high pressure ratio.,For low and medium gas volume.	For low and medium pressures.,For large volumes.
