It uses the adsorption and desorption technology of molecular sieve. The oxygen generator is filled with oxygen molecular sieve, which can absorb nitrogen in the air when it is pressurized. The remaining unabsorbed oxygen is collected and becomes high-purity oxygen after purification. The adsorbed nitrogen is discharged back to the ambient air when the molecular sieve is depressurized, and then it can adsorb nitrogen and produce oxygen when it is pressurized next time. The whole process is a cyclic dynamic circulation process, and the molecular sieve does not consume.
