Pneumatic Basics

Pneumatics is defined as "using pressurized gases to do work." Pneumatic systems are based on the controlled use of compressed air as a source of stored potential energy. By controlling how the air is released, the energy can be turned into movement. Pneumatics are used in handheld power tools, automatic doors, and conveyor systems. They are also used in aircraft for landing gear, flaps, and other instruments. The air brakes on buses and trucks are pneumatic, as well as some exercise machines. Typically, pneumatic systems are more flexible, less costly, and more reliable than many other types of electric motors.
