Oxygen generator working principle: using molecular sieve physical adsorption and desorption technology. The oxygen generator is filled with molecular sieves, which can adsorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected, and it becomes high-purity oxygen after purification.

The principle of oxygen production of a household oxygen generator is as follows:
1. The principle of molecular sieve;
2. Principle of polymer oxygen-rich membrane;
3. The principle of electrolysis of water;
4. The principle of chemical reaction oxygen production.

Molecular sieve oxygen generator is the only mature oxygen generator with international and national standards.
