Pneumatics is a branch of engineering that deals with the use of compressed air to perform work. It involves systems that use air pressure to move or control machinery, making it essential in various applications, such as industrial automation, robotics, and construction equipment. Pneumatic systems typically consist of components like compressors, valves, and actuators. These systems are favored for their simplicity, speed, and safety. Unlike hydraulic systems that use liquids, pneumatics relies on air, which is abundant and non-toxic. This makes pneumatic tools, such as air drills and impact wrenches, lightweight and easy to handle, enhancing productivity in many work environments.
