The principle is to use air separation technology.
Oxygen concentrator is a kind of machine to produce oxygen, firstly, the air will be compressed with high density and then make use of the difference of condensation point of each component in the air to make gas-liquid separation at a certain temperature, and then further distillation and get.
Adopting the adsorption performance of molecular sieve, through the physical principle, with a large displacement oil-free compressor as the driving force, the air in the separation of nitrogen and oxygen, and finally get a high concentration of oxygen. This type of oxygen generator produces oxygen rapidly and has high oxygen concentration, which is suitable for oxygen therapy and oxygen health care for all kinds of people. The power consumption is low.

Precautions for using an oxygen concentrator:
1. In order to prevent a power outage or a possible failure of the oxygen concentrator, those who are in urgent need of oxygen and those who are critically ill must be configured with other back-up oxygen-supply devices, such as: oxygen cylinders, oxygen bags and so on. Although the oxygen concentration of the oxygen concentrator can be as high as 96%, it is only suitable for oxygen supplementation, and should not be considered for life support or life extension at present.
2. Possible electric shock hazard. In the event that the oxygen generator needs to be repaired, the machine should not be disassembled selfishly, but should be repaired by qualified maintenance personnel. Before operating the oxygen concentrator, you should read the instruction manual carefully before using it.
3. During oxygen therapy, if you have a severe headache, blue fingernails or fingertips, panic attacks, drowsiness, or irregular breathing, stop using the machine immediately and contact your doctor as soon as possible.
