(Greek:which means "breath") is a branch of physics applied to technology that makes use of gas or pressurized air.
Pneumatic systems used extensively in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically powered compressor powers cylinders, air motors, and other pneumatic devices.
