An oxygen concentrator is a device that concentrates the oxygen from a gas supply (typically ambient air) by selectively removing nitrogen to supply an oxygen-enriched product gas stream. Two methods in common use are pressure swing adsorption and membrane gas separation.
High oxygen purity 93%+-3%..
For this device, 5 flows can work independently by adjust the flow knob,and also support combine use .The separate flowmeter minimum scale can arrive 0.125L/Min，combine used maximum flow rate less than the oxygen flow rate at oxygen outlet ,It is available for children and adults to choose to use.
