Pneumatics, a subsection of an area called fluid power, is the use of pressurized air to effect mechanical motion. Fluid power is the technology of exploiting the properties of fluids to generate control and transmit power as a result of the pressurization of fluids

Pneumatic power is used in industry, where it is common to have industrial factory unit plumbed for compressed air. For other uses of this term see Industry (disambiguation An industry (from Latin industrius, "diligent industrious" Compressed air It also has applications in, among other things, dentistry, construction, and mining. Dentistry' is the "evaluation diagnosis prevention and/or treatment (nonsurgical surgical or related procedures of diseases disorders and/or conditions of the oral cavity In the fields of Architecture and Civil engineering, construction is a process that consists of the Building or assembling of Infrastructure Mining is the extraction of valuable Minerals or other geological materials from the earth usually (but not always from an Ore body Pneumatic power users need not worry about hazardous leakages as the fuel is commonly just air, although other compressed gases, such as carbon dioxide, may be used. Carbon dioxide ( Chemical formula:) is a Chemical compound composed of two Oxygen Atoms covalently bonded to a single

Comparison to hydraulics

Both pneumatics and hydraulics are applications of fluid power. Pneumatic tools or air tools are Tools driven by gas usually Compressed air supplied by a Gas compressor. A pneumatic drill or jackhammer is a portable percussive Drill powered by Compressed air. A nail gun, nailgun or nailer is a type of Tool used to drive nails into Wood or some other kind of material A switch is a mechanical device used to connect and disconnect an electric Circuit at will A pneumatic actuator converts energy (in the form of Compressed air, typically into motion A gas compressor is a mechanical device that increases the Pressure of a Gas by reducing its Volume. A vacuum pump is a device that removes gas molecules from a sealed volume in order to leave behind a partial Vacuum. A barostat is a device used to maintain constant pressure in a closed chamber Neurogastroenterology is a research area in the field of Gastroenterology which regards interactions of the central nervous system ( Brain) and the Gut - Cable jetting is a technique to install cables in ducts It is commonly used to install cables with Optical fibers in underground Polyethylene ducts and is an alternative Pneumatic tubes (or capsule pipelines; Lamson tubes) are systems in which cylindrical containers are propelled through a network of tubes by Air brakes are used in Trucks Buses trailers, and Semi-trailers. This article is about the semi-truck For the North American use of the word see Pickup truck. An air brake is a conveyance braking system applied by means of compressed air. A train is a connected series of vehicles that move along a track ( Permanent way) to transport freight or passengers from one place to another A Compressed air engine is a Pneumatic actuator that creates useful work by expanding Compressed air. Lego pneumatics is a variety of Lego bricks which utilise air pressure and specialised components to perform various actions utilising the principles of Pneumatics This article is about pipe-based cannons and similar which use air pressure or combustion of a gaseous fuel or both to launch large projectiles at low speed "Air rifle" and "Air pistol" redirect here For other uses see Air gun (disambiguation An air gun ( air rifle The Holman Projector was an anti-aircraft weapon used by the Royal Navy during World War II, primarily between early 1940 and late 1941 Fluid power is the technology of exploiting the properties of fluids to generate control and transmit power as a result of the pressurization of fluids Pneumatics uses air, which is compressible, while hydraulics uses relatively incompressible liquid media such as oil. For the mechanical technology see Hydraulic machinery and Hydraulic cylinder Hydraulics is a topic of science and Engineering 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).

Pneumatic Logic

Main article: Fluidics

Pneumatic logic systems are often used to control industrial processes, consisting of primary logic units such as:

Pneumatic logic is a reliable and functional control method for industrial processes. Fluidics (also known as Fluidic logic) is the use of a Fluid or compressible medium to perform analog or Digital operations similar to those In Logic and/or Mathematics, logical conjunction or and is a two-place Logical operation that results in a value of true if both of In recent years, these systems have largely been replaced by electrical control systems, due to the smaller size and lower cost of electrical components. Pneumatic devices are still used in processes where compressed air is the only energy source available or upgrade cost, safety, and other considerations outweigh the advantage of modern digital control.
