As soon as power is connected, the air is taken in and compressed by oilless air compressor through filtering, then the compressed air goes through the cooler and it is cooled. After that, the air is taken into absorption tower by control valve and the oxygen can be separated in the absorption tower. At the same time, the high purity oxygen is collected into the oxygen tank, and it goes through the flow meter and humidifier, finally theoxygen that meets medical standards can be supplied. Oxygen is generated by pure physical method.The concentrator can supply 1-2 patients simultaneously, with steady oxygen flowing out and reliable, adjustable flow. The device is capable of providing oxygen flow up to 5 LPM. The concentration of supplied oxygen is from 90%-96%. The key parts of the generator adopt anti-tiring and anti-aging design, and the planned life of the whole generator reaches up to 20,000 hours. The weight of Jay-5 is around 25kg (~55lbs). There is no influence on indoor oxygen percent during the generator operating.JAY-5 medical oxygen concentrator contains the following items: One (1) Jay-5 Oxygen Concentrator Unit One (1) AC Power Supply One (1) Nasal Oxygen Tube One (1) Humidifier One (1) Operation Manual (View less)
