Pneumatics is a branch of engineering that deals with the study and application of pressurized gases, typically air, to perform mechanical work. It involves the use of compressed air to create motion or force, making it a versatile and energy-efficient technology widely used in various industries. Pneumatic systems often consist of components like compressors, valves, cylinders, and actuators, and they find applications in areas such as manufacturing, automation, transportation, and more due to their reliability, simplicity, and ease of control.
