【 Auto cooling fan 】 The escort for your 'oxygen.
auto oxygen way can be divided into molecular sieve type automotive, chemical, oxygen-rich membrane automotive and electronics. Molecular sieve type car: is a kind of advanced technology for gas separation. Physical methods ( PSA method) Directly to extract oxygen from the air, the system of the box, fresh and natural, zui oxygen pressure of 0. 2 to 0. 3MPa( The 2 ~ 3 kg) , there is no such as high pressure and explosive dangerous; Chemicals car: adopt reasonable agent. In certain situations. Can really meet some urgent need of consumers. But as a result of poorly equipped. Operating trouble. The cost is higher. Every oxygen requires a fee. Can't use many defects, such as continuous. Oxygen cure don't adapt to the family! Oxygen membrane cars: the car using membrane oxygen, nitrogen molecules in the air by membrane filtration, 30% export oxygen concentrations, the advantages of small volume, small electricity consumption, etc. But by this way of oxygen generation machine is made of 30% of the concentration of oxygen, can be used for long-term oxygen therapy health care, and severe hypoxia condition required for emergency use only medical high concentration of oxygen. Suggest you try the light molecular sieve type car, low noise, high oxygen concentration, imported compressor, high molecular sieve's adsorption performance, not only ensure the product quality and prolong service life.
