Classification of working principle of oxygen concentrator


Electronic oxygen concentrator
Electronic oxygen concentrator are more common in pharmacies. They use the process of oxidation and reduction of oxygen in the air in a solution, so it will not produce dangerous hydrogen like oxygen produced by electrolysis of water. The whole machine runs quietly, but this kind of product requires very strict requirements during the handling and use. It is never allowed to tilt or invert, otherwise the solution will flow into the oxygen tube and spray into the nasal cavity, causing serious damage to the user. At the same time, other oxides are easily produced in the oxygen production process, and the produced oxygen contains chemical substances. This type of oxygen production method consumes more power.

Molecular sieve oxygen concentrator
Molecular sieve oxygen concentrator is an advanced gas separation technology. The physical method (PSA method) directly extracts oxygen from the air. ), there is no danger such as high pressure and explosion.

Chemical oxygen concentrator
It adopts a reasonable pharmaceutical formula and can be used on specific occasions, which can indeed meet the urgent needs of some consumers. However, due to the simple equipment, troublesome operation, and high cost of use, a certain cost is required for each oxygen inhalation, and many defects such as inability to continuous use are not suitable for home oxygen therapy.

Oxygen-enriched membrane oxygen concentrator

This kind of oxygen concentrator adopts membrane oxygen production method. Through membrane filtration of nitrogen molecules in the air, the oxygen concentration of the outlet reaches 30%. It has the advantages of small size and low power consumption. However, the oxygen produced by this kind of oxygen production method is 30% oxygen, which can be used for long-term oxygen therapy and health care. However, the first aid required under severe hypoxia can only use medical high-concentration oxygen.
