The oxygen making principle of the oxygen making machine is as follows:
1, molecular sieve principle; 2. The principle of polymer oxygen-enriched membrane; 3. The principle of electrolytic water; 4. Principle of oxygen production by chemical reaction.
Molecular sieve oxygen generator is the only mature oxygen generator with international and national standards.
Working principle of molecular sieve oxygen generator;

Using 220V alternating current as power supply, air as raw material and high-quality molecular sieve, high-purity oxygen with a purity of 93% 3% meeting the medical oxygen standard was prepared by pressure swing adsorption separation (PSA method) at room temperature.

Therefore, domestic oxygen generators and hospital oxygen generators are only different in oxygen concentration, and both use the principle of pressure swing adsorption to produce oxygen. The oxygen concentration of oxygen supply in large centers of hospitals can reach above 98%, and the general oxygen concentration in families is 93% 3%.
