A pneumatic system is a technology that uses compressed air to perform work. It consists of various components like compressors, valves, and cylinders that work together to move objects or control machinery. For example, in factories, pneumatic systems are often used to power tools and equipment, making tasks easier and more efficient. These systems are popular because they are generally safe and easy to maintain. Unlike electrical systems, which can pose shock hazards, pneumatic systems rely on air pressure, making them less risky in certain environments. Common applications include automotive assembly, packaging machines, and robotic arms.
