Oxygen concentrators are a class of machines that produce oxygen based on the principle of air separation.First, the air is compressed with high density, then the different condensation points of each component in the air are used to separate the gas and liquid at a certain temperature, and then the air is distilled further.

The general working principle of oxygen concentrators is to separate nitrogen from oxygen in air by using the adsorption performance of molecular sieve and using large displacement oil-free compressor as power through physical principle, and finally obtain high concentration of oxygen.This type of oxygen concentrators produces oxygen rapidly and has a high oxygen concentration, which is suitable for oxygen therapy and oxygen health care of all kinds of people.Low power consumption, only 18 cents an hour, low use price.

The operating principles of industrial and household oxygen concentrators are as follows:

The principle of industrial oxygen concentrators is to use air separation technology. First, air is compressed with high density and then separated from liquid and gas at a certain temperature by using the different condensation points of each component in the air, and then distilled further. Oxygen used in industry is usually obtained by this physical method.Large air separation plants are generally designed to allow gases such as oxygen and nitrogen to displace temperature sufficiently for distillation during climbing and descending.

Operating principle of domestic oxygen concentrators: molecular sieve physical adsorption and desorption technology is used. Molecular sieve is filled in the oxygen generator and nitrogen in the air can be absorbed under pressure. The remaining unabsorbed oxygen is collected and purified to become high purity oxygen.The molecular sieve exhausts the adsorbed nitrogen back into the ambient air when depressurizing, and then absorbs the nitrogen and generates oxygen at the next pressure. The whole process is a cyclical and dynamic cycle, and the molecular sieve is not consumed.
