The principle is the use of industrial oxygen air separation technology

The principle is the use of industrial oxygen air separation technology,first, a high density compressed air to the condensation point of the air in the re-use of the components is different so air separate unit molecular sieve  that in the gas and liquid from a certain temperature,activated molecular sieves and further distillation derived; home oxygen works: the use of molecular sieve physical adsorption and desorption techniques. molecular sieves 4a  Filling the molecular sieve oxygen generator can be adsorbed nitrogen pressurized air, the remaining oxygen is not absorbed is collected, after purification was turned into high-purity oxygen.
