single stage air compressor :When the piston moves down inside the cylinder, the air enters the space above thanks to the difference between the atmospheric pressure and the pressure inside the cylinder. The air is then compressed as the piston moves upwards. two stage air compressor : Two-stage compressors take the air in from the atmosphere just like single-stage units, but as you can see on the picture they have two cylinders instead of one. multi stage air compressor :The intake of air in the first stage gets compressed and then it is passed over a cooler to achieve a temperature very close to ambient air. This cooled air is passed to the intermediate stage where it is again getting compressed and heated.

2. .SINGLE STAGE AIR COMPRESSOR.
 When the piston moves down inside the cylinder,
the air enters the space above thanks to the
difference between the atmospheric pressure and
the pressure inside the cylinder.The air is then
compressed as the piston moves upwards.
 Reciprocating and piston air compressors are
interchangeable terms, and this type of air
compressor is the most common on the market
today.

4. .TWO STAGE AIR COMPRESSOR.
 Two-stage compressors take the air in from the
atmosphere just like single-stage units, but as you
can see on the picture they have two cylinders
instead of one.
 During the first stage, the air is compressed to an
intermediate pressure. After that the majority of
heat is removed, and the air is passed on to another
cylinder where it is compressed to a specified value.

6. .MULTI STAGE AIR COMPRESSOR.
 The intake of air in the first stage gets compressed
and then it is passed over a cooler to achieve a
temperature very close to ambient air.This cooled
air is passed to the intermediate stage where it is
again getting compressed and heated.
 This air is again passed over a cooler to achieve a
temperature as close to ambient as possible.Then
this compressed air is passed to the final or the third
stage of the air compressor
