Oxygen concentrators are classified according to their working principles

Electronic oxygen generator:
Electronic oxygen concentrators are more common in pharmacies. They use the process of oxidizing and reducing the oxygen in the air to precipitate in the solution, so they will not produce dangerous hydrogen like electrolyzing water to produce oxygen. The whole machine runs relatively quietly, but this kind of product has very strict requirements in the process of handling and use, and it is absolutely not allowed to tilt or invert, otherwise its 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 likely to be produced during the oxygen production process, and the produced oxygen contains chemical substances. This type of oxygen production method consumes a lot of power.
Molecular sieve oxygen generator:
Molecular sieve oxygen generator 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 uses it on specific occasions, which can indeed meet the urgent needs of some consumers. However, due to poor equipment, troublesome operation, high cost of use, a certain amount of cost is required for each oxygen inhalation, and many defects such as not being able to use continuously are not suitable for home oxygen therapy.
Oxygen-enriched membrane oxygen generator:
This kind of oxygen generator adopts membrane oxygen production method, through which the nitrogen molecules in the air are filtered by the membrane to reach the concentration of 30% oxygen at the outlet. It has the advantages of small size and low power consumption. But the machine that adopts this oxygen generating mode makes 30% concentration of oxygen, which can be used for long-term oxygen therapy and health care, while the first aid required in a severe hypoxic state can only use medical high-concentration oxygen.
