A.C. electric motor

compressed air

petrol engine

diesel engine

These are used to dampen pulsations ,

These act as reservoir to- take care of sudden demands

These increase compressor efficiency

These knock out some oil and moisture

sun

shade

rain

enclosed room

Power consumption per unit of air delivered is low

Volumetric efficiency is high

It is best suited for compression ratios around 7:1

The moisture in air is condensed in the intercooler

employing intercooler

by constantly cooling the cylinder

by running compressor at very slow speed

by insulating the cylinder
