The Miniature Gas Pressure Regulator is a small, lightweight device designed to handle a 350bar gas inlet and provide a 0.5bar outlet, making it ideal for typical hydrogen fuel cell applications. The gas pressure regulator includes an integrated gas pressure sensor, allowing users to monitor the remaining fuel pressure in the gas cylinder in real time. The package also comes with a refueling kit, which includes a 2m stainless steel hose and adapter, for easy refilling from an industrial gas tank.
