Pneumatics, from the Greek πνευματικός (pneumatikos, coming from the wind) is the use of pressurized air in science and technology.
Pneumatics
are used in a variety of settings. In dentistry applications, pneumatic drills are lighter, faster and simpler than an electric
drill of the same power rating (because the prime mover, the compressor, is separate from the drill and pumped air is capable of rotating the drill bit at extremely high rpm's). Pneumatic devices are also used where
electric motors cannot be used for safety reasons, such as mining applications where rock drills are powered by air motors to preclude the need for electric motors deep in the mine where explosive gasses may be present.
Pneumatic systems
are used in
manufacturing to control industrial processes. These systems started being replaced in the
1990s with
Distributed Control Systems, where costs permit.
Industrial pneumatics may be contrasted with hydraulics, which uses noncompressible liquid media such as oil, or water combined with soluble oil, instead of air. Air is compressible, is considered to be a fluid, and most industrial applications use approximately 80 to 100 pounds per square inch (psi) pressure, as compared to hydraulics which are comonly used from 1,000 to 5,000 psi, and in some cases 10,000 psi and higher. Both pneumatics and hydraulics are applications of Fluid Power.
Common industrial pneumatic components include:
