Pneumatics is the use of pressurized air to effect mechanical motion. Pneumatics is employed 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). Pneumatic transfer systems are employed in many industries to move powders and devices.
Pneumatic tubes can carry objects over distances. Pneumatic devices are also used where
electric motors cannot be used for
safety reasons, such as deep in a mine where explosive dust or
gases may be present.
