Pneumatic components are used broadly in industrial automation and are normally powered by compressed air. Pneumatic systems use actuators such as cylinders that are usually controlled via manual, air-pilot, or solenoid valves, and are designed in, when they can supply a low cost, more pliable, or safe alternative to electric actuators.
Pneumatic components fall under the umbrella of fluid power systems. These pneumatic systems work by using pressurized air to activate cylinders, solenoid valves, and other machine components. Benefits of incorporating pneumatics into your machine build include reliability, safety, and easy integration.
