Why Do Medical Oxygen Concentrators Use Molecular Sieves?

The main reasons why medical oxygen concentrators use molecular sieves are as follows:

1. Efficient separation:

Molecular sieves can effectively separate oxygen and nitrogen in the air. This is achieved by physical adsorption, that is, molecular sieves have different adsorption capacities for oxygen and nitrogen. Under pressurized conditions, nitrogen molecules are more easily adsorbed, while oxygen molecules are less adsorbed, thus being separated.

2. High-purity oxygen:

Molecular sieve technology can be used to obtain high-purity oxygen, usually with a purity of more than 93%, which meets the requirements of medical use.

3. Safety:

Compared with traditional oxygen supply methods (such as high-pressure oxygen cylinders and liquid oxygen), molecular sieve oxygen concentrators are safer. High-pressure oxygen cylinders and liquid oxygen have risks in transportation and storage, while molecular sieve oxygen concentrators avoid these problems.

4. Economical:

Molecular sieve oxygen concentrators reduce dependence on high-pressure oxygen cylinders or liquid oxygen, reducing long-term use costs. In addition, since it can produce oxygen on site, no additional transportation costs are required.

5. Continuity:

Molecular sieve oxygen generators can run continuously and produce oxygen uninterruptedly. Usually a double-tower structure is adopted, when one tower is in the adsorption state, the other tower is in the regeneration state, so as to achieve continuous oxygen supply.

6. Simple maintenance:

The maintenance of molecular sieve oxygen generators is relatively simple. Regularly replacing the molecular sieve and keeping the system clean can ensure the normal operation of the equipment.

7. Flexibility:

Medical molecular sieve oxygen generators can adjust the oxygen flow and purity as needed, suitable for different medical needs.

8. Reliability:

Molecular sieve technology is mature and reliable, which can ensure the quality and stability of oxygen.

In summary, molecular sieves have been widely used in medical oxygen generators because of their high efficiency, safety, economy, flexibility and reliability. They are not only used in hospitals, but also widely used in home care and other occasions requiring high-purity oxygen.
