Features:Molecular sieve: high efficiency lithium sieve, strong adsorption, high oxygen yield, strong stabilityCompressor: pure copper oil-free air double cylinder compressor, small energy consumption, strong power, low noise, fast heat dissipationLow noise: the measured noise is as low as 42 dB, and the oxygen concentration is high, which can still be maintained in continuous operationIntelligent Control:IMD beautiful large color panel, easy to operate, large color LED screen, Flow regulation, voice broadcast function,timer operation function and with infrared remote control, let itbe easier and more convenient.2in1 Oxygen in-ha-la-tion ato-mi-zation :Special interface for ato-miza-tion,Oxygen generation and ato-miza-tion are carried out at the same timeSpecifications:This is a professional oxygen generator developed by the German research and development team. It has the advantages of high oxygen concentration and stable oxygen output. It is suitable for home and vehicle scenarios, so that you can breathe high-quality air at home and outdoor.Power supply:AC110V60Hz for US,AC220V50Hz for EUOutput power:150VAOxygen concentration: 35%-90%(Adjustable by flow)oxygen flow:1~7L/minNoise:≤50dB(A)Net weight:5.5kgOutline size: 305x180x300mmSafety system:Current overload protectionHigh temperature of compressor, shutdownElectrical classification:ⅡOperating mode: continuousPackage Includes:1set* Oxygenerator1roots *Power cord1set* Nebulizer1sets *Nasal oxygen tube2sets*FilterScreen2sets*Filter2sets*Filter cotton2sets*Fuse1set Remote control1cop*Instruction
