Pneumatics - Wikipedia

Pneumatic systems used 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. A pneumatic system controlled through manual or automatic solenoid valves is selected when it provides a lower cost, more flexible, or safer alternative to electric motors and actuators. Pneumatics also has applications in dentistry , construction , mining , and other areas. Pneumatic systems in fixed installations, such as factories, use compressed air because a sustainable supply can be made by compressing atmospheric air. The air usually has moisture removed, and a small quantity of oil is added at the compressor to prevent corrosion and lubricate mechanical components.

Compressed Air Absolute viscosity: It is defined by the force required to move a flat plate of unit area at unit distance from a fixed plate with unit velocity when the space between the plates is filled with a fluid whose viscosity is to be measured. Smaller or stand-alone systems can use other compressed gases that present an asphyxiation hazard, such as nitrogen -often referred to as OFN oxygen-free nitrogen when supplied in cylinders. How does a pilot operated check valve differ from a simple check valve.
