Jupiter Pneumatics R13904 Pneumatic Regulator

Jupiter Pneumatics R13904 Pneumatic Regulator is a pressure-regulating device designed for use in compressed-air systems. The model R13904 lists a 225 PSI setpoint and an adjustable output range from 7 to 140 PSI, enabling precise downstream pressure control for actuators, valves, and pneumatic tooling. In typical applications, regulators like the R13904 provide stable pressure to automation equipment, bench-top test rigs, and other pneumatic circuits, helping maintain consistent performance as supply conditions change. The 7–140 PSI adjustment range covers low to moderate pressures common in automation and tooling tasks, while the 225 PSI figure denotes the reference setpoint associated with this model. When integrating this regulator, verify that the downstream devices require pressures within the 7–140 PSI range and ensure compatibility with your system’s fittings and tubing.
