Does the oxygen generator produce oxygen or filter oxygen ?

The oxygen generator uses the characteristic of different condensation points of different components in the air to separate the air from gas and liquid, and obtain oxygen through further rectification. Among them, molecular sieve is the core component of the oxygen generator, and it is also the key step of the oxygen generator.

The oxygen generator makes full use of the physical adsorption performance of molecular sieves, and uses oil-free compressors as power to separate nitrogen and oxygen in the air. The final result is high-concentration oxygen. As for the filtration system that is mistaken for the oxygen generator to filter oxygen, it is the pre-step of the oxygen generator. It can ensure that the air entering the molecular sieve is clean enough, and the final output oxygen concentration and safety are better guaranteed.

While outputting high-concentration oxygen, the molecular sieve will discharge the adsorbed nitrogen into the air during the decompression, and the next pressurization will re-adsorb the nitrogen to produce oxygen. In this oxygen production cycle, the molecular sieve will not be consumed.

However, it should be noted that although the core component of molecular sieve is not consumed naturally, the performance of oxygen generators of different qualities after working for a long time is significantly different. The most intuitive manifestation is that the oxygen concentration will attenuate, which directly leads to the deterioration of the oxygen inhalation effect, and even harms the health of the patient.

Therefore, in the choice of oxygen concentrator, users should choose the appropriate oxygen concentrator according to their own needs. For non-therapeutic consumers, a small-capacity oxygen generator can achieve results. But for patients suffering from chronic obstructive pulmonary disease or similar serious diseases, only by choosing a medical-grade oxygen generator can they benefit from home oxygen therapy, not just a kind of psychological comfort. Taking COPD patients as an example, the reason why we need to use medical-grade oxygen concentrators is because from the perspective of treatment effects, COPD patients receiving home oxygen therapy must inhale oxygen for a long time to achieve significant oxygen therapy effects.



Therefore, in the choice of oxygen concentrator, it is necessary to pay attention to the two points of oxygen concentration and continuous working performance. Only when the time requirement of oxygen therapy can be met can the expected effect of home oxygen therapy be exerted.
