Pneumatics includes the fittings, tubes, hoses, actuators, and other components that make pneumatic power possible. Pneumatic systems use compressed gases to generate mechanical energy that operates machinery. Pneumatic energy can be used for air tools, blow guns, pick and place industrial applications, and more. In general, pneumatic systems are used in applications requiring a lesser force and accuracy than hydraulic systems. Pneumatic system s may pose lower risks to health and safety than other energy systems used in industrial processes such as those utilizing electrical equipment.
