Thanks to the new structure, the pressure regulator PRX 05 develops efficiency and stability that is usually obtained with much bigger diaphragm regulators. Performance which becomes vital when the system is connected to patients in need of high and stable capacity. PRX 05 can be directly fixed to the tank and also has a medical gas connection entrance as required by the European standards. The calibration is fixed. The pressure control of the tank (contents) can be read with a precision gauge. The structure is made completely of chromed brass. It provides a set safety valve and an ISO 1/4 " gas connection and a 6 mm [0.23 in] diameter inlet.
