What does pneumatics mean?
Pneumatics is the study and practical application of air and other gases under pressure. In engineering, it describes systems that use compressed air to generate movement, transmit power, or control equipment. Such systems appear in industrial machinery, vehicle braking and suspension, medical equipment, packaging machines, and automation controls. Pneumatic systems are valued for their simplicity, their ability to deliver rapid and reliable motion, and their suitability in environments where electrical sparks could be hazardous. The term is also used more broadly for the technology itself, as when someone discusses the pneumatics of a factory. Although pneumatic equipment shares the basic principle of transmitting pressure with hydraulic equipment, it uses a compressible gas rather than an essentially incompressible liquid. The word is most often encountered in technical, engineering, industrial, and automotive contexts.
nounThe branch of science and engineering concerned with the properties and use of air and other gases, especially the mechanical uses of compressed air. The word also refers to the systems and mechanisms that operate using compressed air or other pressurized gases.
- The branch of science and engineering dealing with the mechanical properties and applications of air and other gases.
- The systems, equipment, or mechanisms that use compressed air or another pressurized gas to transmit force and operate machinery.
"Pneumatics is used to control industrial machinery with compressed air."
"The course introduces the principles of pneumatics and industrial control systems."
"The factory replaced several electric motors with a network of pneumatics."
The standard plural form is the same as the singular form. It is commonly used with a singular verb when it means the field as a whole: "Pneumatics is taught in the engineering department."
"The students studied pneumatics before designing the automated production line."
Pneumatics turns the invisible force of compressed air into a remarkably versatile way to move, control, and power machines.

Where does pneumatics come from?
Pneumatics derives from the Greek "pneumatikos", meaning "of or relating to wind or breath", which in turn comes from "pneuma", meaning wind, breath, or spirit. The related Greek word "pneumon" refers to the lungs, reflecting the older association between air and breathing. The modern scientific sense developed through the study of air pressure and the mechanical uses of compressed air, and the word has cognates in other European languages.

How pneumatics is actually used
Usually treated as a plural noun, although it is regularly used in the singular form "pneumatics" when referring to the field as a whole. It is distinct from hydraulics, which concerns liquid pressure.
Easily confused with pneumatics
Pneumatics uses air or other pressurized gases, whereas hydraulics uses an incompressible liquid, usually oil or water.
