Pneumatics deals with systems that use compressed air or gas to generate mechanical motion or perform work. Pneumatics involves the control and transmission of energy through the use of compressed air or gas, typically using components such as air compressors, valves, actuators, cylinders, fittings, tubing, and hoses. Pneumatic systems are widely used in various industries for automation, manufacturing, transportation, and other applications where precise and reliable control of mechanical movements and processes is required. Pneumatics offer advantages such as fast and responsive operation, simplicity, cleanliness, and versatility in a wide range of applications.
