The core hardware of the oxygen concentrator includes compressors, molecular sieves, four-way valves, filters, heat dissipation and noise reduction systems.
Among them, the quality of the compressor determines the ability of the oxygen generator to work continuously, the molecular sieve determines the oxygen production efficiency of the oxygen generator, the four-way valve is a nitrogen and oxygen exchanger, the filter is divided into 1-3 stages to remove impurities, and the radiator It is good for the life of the machine, and the noise reduction system determines the size of the noise.
How much the molecular sieve is filled determines the ability to continuously supply oxygen. The molecular sieve will wear out when it is working. If the filling technology is not tight, the oxygen concentration will drop after the machine is used for 1-2 years. Some machines do not have an alarm function, which is difficult for ordinary consumers. Discover.
The four-way valve has a total of 4 holes, which are connected to the molecular sieve molecular sieve, the compressor, the heat dissipation copper pipe, and the exhaust pipe. The role is to retain oxygen, remove nitrogen, and maintain the continuous oxygen supply of the machine.
If your machine is turned on and the compressor is running normally, but the molecular sieve is not working (alternating beeps), the four-way valve is probably damaged.
The filter is divided into 1-3 level filters, the first level is a washable sponge body with relatively large holes, which plays the role of primary filtering air impurities. The second level is a filter paper with a higher density, with smaller holes, which can filter smaller impurities in the air. The third stage is the oxygen outlet filter, which is fixed inside the machine and cannot be replaced by ordinary consumers. As long as the first and second stages are well maintained, the third stage is within the life of the oxygen generator and does not need maintenance.
