Pneumatic devices create and use compressed air for their functionality, and rock drills, pavement breakers, riveters, forging presses, paint sprayers, blast cleaners, and atomizers are all common examples. Compressed air power is a safe, economically-friendly, and flexible option which causes no spark hazards in an explosive system. Furthermore, it is usable in wet conditions without the risk of electric shock. Pneumatic devices are also able to fill a storage tank for occasional use and do not require return lines. Additionally, it is possible to connect components like a valve or cylinder and piston to one another through a pipe, tubing, or a flexible hose. Pneumatic devices also can perform actions such as changing the movement of an actuating piston in a cylinder without shock by manipulating the valves. Air systems like these offer flexibility, speed, and motion control, utilizing relief valves to protect equipment. They are also easy to operate and have few moving parts which makes them reliable and easy to maintain.
