Pneumatic systems are a vital part of marine automation because compressed air is used in controlling the movement of machinery on ships. It includes pneumatic valves, cylinders, actuators, and air compressors all working together for smoother and safer operation. In most applications like cargo handling, ventilation, and security systems, simple design, quick response, and reduced risk of fire make them popular. Despite their limitations-the air leaks and lesser force than hydraulics-they have seen use in various applications of marine and industrial projects largely because of their reliability and ease of maintenance.
