100% brand new and high quality Features: It is mainly used in the oxygen supply system, which is used by emergency oxygen and oxygen inhalation; it can also used in the flow control devices of scientific research institutions, industrial, mining and other inhalation. Pressure Reducing Valve: The theme of the pressure reducing valve, high toughness, wear resistance, corrosion resistance, better sealing safety. Fine Pressure Gauge: the pressure gauge is thick and anti-fall design, clear scale and high sensitivity. Gas Filter: double protection, more energy efficient, more economical, safer to use; Precision machining is used to ensure the machining accuracy of each part. Tide Bottle: Removable and washable, more hygienic. Built-in filter to prevent impurities from entering. Working Principle: The role of the oxygen inhaler is to provide continuous constant pressure and flow. The bottle plug-in oxygen inhaler uses its own pressure reducing device to reduce the high pressure in the oxygen cylinder (15Mpa pressure when the bottle is full) to a low pressure suitable for use (0.2~0.2Mpa), and then output after being moistened by water . Since the wall plug-in oxygen inhaler has an input pressure of 0.2~0.4Mpa, it does not need to be decompressed and can be directly output. Operation method: 1. Add distilled water to the humidification cup. The water level in the bottle cannot be higher than the upper water line, but not lower than the lower water line. It is forbidden to use normal saline instead. 2. Before inserting the inhaler into the oxygen supply terminal socket, turn off the flow adjustment switch and adjust the direction of the oxygen quick plug, and then insert the quick plug into the oxygen supply terminal socket. When you hear a click sound and see the oxygen supply terminal When the locking sleeve of the socket slides automatically, it indicates that the quick plug and the oxygen supply terminal socket have been connected and locked. 3. Insert the oxygen inhalation tube into the oxygen supply connector before supplying oxygen, and then turn the flow adjustment switch counterclockwise to turn on the origin, so that the float rises slowly (the scale line aligned with the center of the float is the flow reading, and the unit is liters/min) , The oxygen supply can be adjusted accordin Specification: Product name: Buoy type oxygen inhaler Input pressure: 15Mpa Output pressure: 0.25Mpa Flow adjustment range: 1-10L/min Safety valve: 0.5Mpa automatic exhaust Imported thread: G5/8 Export thread: M12x1 With humidification bottle device Material: PC,Glass,Metal Color: Transparent The color of the pressure gauge surface will be sent in random Size:app. As picture shown Quantity: 1 pc Note: Transition: 1cm=10mm=0.39inch No retail package.
