The Jenny 360-1109 Pressure Regulator is designed to maintain consistent output pressure in compressed air systems. This regulator works by adjusting downstream pressure through an internal diaphragm and spring mechanism that responds to changes in inlet pressure, allowing only the desired amount of air to pass through. By keeping pressure at a set level, it protects tools and equipme... https://www.wholetoolbox.com/jenny-360-1109-pressure-regulator
