Electronic oxygen generator

Electronic oxygen generator is common in pharmacies. They use a process in which oxygen in the air is oxidized and reduced in solution, so that dangerous hydrogen is not generated as in electrolyzed water. The whole machine runs quietly, but these products are very strict in the process of handling and use. Tilt or invert are not allowed, otherwise the solution will flow into the oxygen pipe and spray into the nasal cavity, causing serious damage to the user. At the same time, other oxides are easily produced by using the oxygen production process, and the produced oxygen contains chemical substances, and such oxygen production methods consume a large amount of electricity.

Molecular sieve oxygen generator

Molecular sieve oxygen generator is an advanced gas separation technology. The physical method (PSA method) extracts oxygen directly from the air. It is ready-to-use, fresh and natural. The maximum oxygen pressure is 0.2-0.3 MPa (that is 2 to 3 kg). There is no danger of high pressure and explosion.

Chemical oxygen generator

It is a reasonable formula and can be used in certain occasions to meet the urgent needs of some consumers. However, due to the simplification of the equipment, the operation is troublesome, the use cost is high, and each time the oxygen is absorbed, a certain cost is required, and the defects cannot be continuously used, and it is not suitable for the home oxygen therapy.

Oxygen-rich membrane oxygen generator

The oxygen generator adopts membrane oxygen generation method, and filters the nitrogen molecules in the air through the membrane to reach a concentration of 30% of the outlet oxygen, and has the advantages of small volume and small power consumption. However, the machine using this oxygen production method produces 30% oxygen, which can be used for long-term oxygen therapy, and the first aid required in severe hypoxia can only use medical high concentration oxygen.
