Technical parameter: Model: COX-015 Rated voltage: AC110V/ 220V 50Hz Oxygen Method: Seventh Generation PSA Input Power: 105W Inhalation: headset type,nasal tube running noise: ≤48dB Oxygen concentration: 30% -90% Product Dimensions: 302 × 168 × 325mm Out of gas: Three ESC Product Net Weight: 5.2KG Negative oxygen ions: ≥6 million particles / cm³ Display Control: LED timer display, smart chip control Treatment: 1. People with increased oxygen consumption: mental workers with excessive brain use, including intellectuals, boss managers, students taking exams; urban people with tight pace of life; drivers of long-distance driving, etc. 2. People with insufficient oxygen utilization capacity: including patients with respiratory tract (nasal sensitivity, asthma, chronic branch), cardiovascular (hypertension, coronary heart disease), cerebrovascular (stroke), hematological disease (anemia, etc.), elderly (Diabetes, etc.). 3. Urban people with insufficient oxygen supply in work and living environment: hotels, hotels, and writing rooms. 4. Oxygen care for the elderly: effectively reduce and reduce the incidence of cardiovascular and cerebrovascular diseases. 5. Respiratory diseases: pneumonia, bronchitis, chronic bronchitis, viral respiratory infections, asthma, emphysema, pulmonary heart disease, etc. 6. Cardio-cerebral vascular diseases: hypertension, heart disease, coronary heart disease, myocardial infarction, cerebral thrombosis, cerebral ischemia, cerebral vertigo, atherosclerosis, etc. 7. High altitude hypoxia: high altitude pulmonary edema, acute mountain sickness, chronic mountain sickness, high altitude coma, high altitude hypoxia and so on. Function of oxygen concentrator: Adjustable oxygen concentration: supply continous flow 1-6L/min adjustable, 30%-90%,(1L: 90%±3 2L: 50%±3 6L: 30%±3 ) Portable and lightweight: only 5.2kg, Could work plug-in home power supply(AC 110V )for continuous working 24 hours a day if you do not set timer. Intelligent Control:IMD beautiful large color panel, easy to operate, large color LED screen, el-ear display, timer operation function and with infrared remote control, let itbe easier and more convenient. Anion:This machine is equipped with ion function, and a "negative" button; the negative ion system can work alone , you can also work simultaneously with theoxygen system;Anion generatorAir vents located in the machine, the exhaust vents discharged into the surrounding space of the machine when working. Multi-layer filter, self-easy to replace:The oxygen system of this product has coarse dust filter, fine dust filter andthree bacterial filtration treatment for the input air respectively, finally, theoxygen is fresh and clean after filtering , and the two front layers filter canbe replaced without disassembing, the user operate it comfortably.
