  "abstract": "This disclosure describes a system for recovering compressed air from the exhaust port of a pneumatic cylinder and directing it into a low-pressure ring main. The arrangement addresses the significant energy loss inherent in conventional pneumatic systems, where exhaust air is typically vented to atmosphere. It details a recovery circuit that manages pressure levels, mitigating the impact on cylinder return speed, and outlines the conditions under which such a system offers a beneficial energy return. The recovered air can then be used by other low-pressure pneumatic consumers within an industrial facility, thereby reducing overall compressed air generation requirements.",
