A Preset Oxygen Regulator made of steel or another form of metal is an essential part of anaesthesia equipment. This fitting controls the flow of oxygen through the pipeline. It has an input pressure of 15MPa. Preset Oxygen Regulator output pressure is between 0.2 and 0.3 MPa. The regulator is designed for use with polycarbonate bottles. The flow control rate can be adjusted between 0 and 15 l/min. The reliability and longevity of this regulator are checked by leakage tests, diameter, strength and design precision.
