Oxygen concentrator bad maintenance method: you can call the after-sales service phone or go to the health care equipment repair store maintenance. Oxygen concentrator is a class of machines to produce oxygen, its principle is to use air separation technology. First of all, the air will be compressed at high density and then use the different condensation point of each component in the air to make it under a certain temperature for gas-liquid separation, and then further distillation and get. It is used for oxygen therapy and oxygen health care for all kinds of people. Low power consumption, the cost of one hour is only 18 cents, low price. Adopting the adsorption performance of molecular sieve, through the physical principle, with large displacement oil-free compressor as the driving force, the nitrogen and oxygen in the air are separated, and finally get the 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. Low power consumption, the cost of an hour is only 18 cents, the use of low price.
