Pneumatics was first documented by Hero of Alexandria in 60 A.D., though the subject had been known before then.
Use
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 pellets. 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.
Examples of pneumatic tools:
pneumatic drill (jackhammer) used by road workers;
Pneumatic tools;
pneumatic switch;
pneumatic actuators;
air compressors;
vacuum pumps;
barostat-systems used in Neurogastroenterology and to research;
electricity;
Cable Jetting - a way to install cables in ducts;
Pneumatic post;
Comparison to Hydraulics
Both pneumatics and hydraulics are applications of fluid power. Pneumatics uses air, which is compressible, while hydraulics uses relatively incompressible liquid media such as oil or water. Most industrial pneumatic applications use pressures of about 80 to 100 pounds per square inch (psi) (500 to 700 kilopascals). Hydraulics applications commonly use from 1,000 to 5,000 psi (7 to 35 MPa), but specialized applications may exceed 10,000 psi (70 MPa).
