This page provides an overview of articles related to pneumatic applications. Pneumatics is the science of transmitting power using compressed air or inert gas. A pneumatic system consists of a compressor, a receiver or air vessel, air treatment devices, pipes and valves and the equipment to be regulated, such as grippers or cylinders. The most commonly used valve-types are solenoid valves, which control the supply of air to the actuators. Because atmospheric air contains airborne dirt, water vapor, and other contaminants, filters and air dryers are recommended to be used in pneumatic systems to keep the compressed air clean and dry. This improves reliability and service life of the components and the system.
