• Compressor: This unit compresses the air which is at atmospheric pressure. The pressure of air increases

• Air reservoir/ Air Tank: This tank stores compressed air which is output of air compressors.

• Moisture seperator: moisture (water vapour ) is seperated. Type-chemical or mechanical

• Air filter-Air pressure regulator-Air lubricator: Filtered,pressure regulated fine particles helps in proper lubrication of sliding or rotary parts of actuator or valves.

• DCV/FCV: These valves direct flow of air,control flow of air,speed of actuators.

• Air actuators:These items are the heart of pneumatic system.These are taking part in obtaining mechanical advantage.These are either linear or rotary actuators.

• Air conducting elements:The compressed air flow through pipes,valves are conducting elements.
