– Reduced preliminary expense


– Reduced maintenance expense


– Higher power operating expense

– Optimum Obligation Cycle = 75%.

Reciprocating compressors are available in dimensions from less than 1 hp to more than 600 hp. Oil much less compressor designs are additionally available for applications calling for a better of air, such as breathing air in hospitals, or for use in food or pharmaceutical production.

Rotating Screw Air Compressors.

– Medium first price.
