Mox Oxygen regulator has a factory preset fixed static outlet pressure of approx. 4.2 kg/Sq.cm (60lbs/sqin) and is fitted with safety valve. Once the flow rate has been set, the regulator will automatically maintain a constant flow rate irrespective of changing volume of cylinder contents. If the oxygen line distal to the regulator should be blocked, the regulator automatically prevents the build up of an excessive pressure in the apparatus and tubing between the outlet of the regulator and the obstruction. A pressure gauge indicates the cylinder contents. NITROUS OXIDE REGULATOR IS ALSO AVAILABL. The Back Pressure Compensated(BPC) flowmeter incorporates a rotary pin valve control to permit adjustment of the flow rate to any desired level between 0-15 ltrs/min.Humidifier Bottle (Nut on Type) is Autoclavable, consist of an unbreakable jar with nut on cap fitted on top inlet and side outlet tubes. The inlet tube ends in a specially designed diffuser from which oxygen is bubbled through water before reaching the outlet
