The molecular sieve, the core component of the PSA oxygen generator, is a porous material that can screen substances at the molecular level, and is mainly composed of zeolite materials. Because it can filter gases of different diameters at the molecular level, people take advantage of this feature and use it to adsorb specific gases, such as oxygen. This is also the core principle of the PSA oxygen generator.

At present, most of the medical PSA oxygen generators use zeolite molecular sieves. This kind of molecular sieve produces oxygen quickly and has high adsorption efficiency. But the disadvantage is that it is easy to be damp, and the molecular sieve after damp will compromise the oxygen adsorption effect, which is likely to cause the oxygen concentration to be out of compliance with the standard. Therefore, in actual work, try to keep the oxygen generator in a ventilated and dry environment, and regularly maintain the oxygen generation system, replace consumables, and prevent the molecular sieve from entering water and oil, which affects the efficiency of molecular sieve. In order to ensure the normal output of the oxygen generator, the manufacturer of the oxygen generator is also obliged to send professional after-sales personnel to do regularly check to test the oxygen concentration, find abnormalities in it, and make adjustments in time.

In the choice of molecular sieve, many people are very fond of imported products. At this point, in fact, it is unnecessary. The domestic ones are not necessarily inferior to foreign ones, and the choice of molecular sieve mainly depends on the grade. The higher the grade, the better the quality.

In addition to the quality of the molecular sieve itself, the filling technology of the molecular sieve is also very important. For example, factors such as the amount of filling, sealing performance, and matching will directly affect the continuous oxygen supply capacity of the PSA oxygen generator. In general,when choosing an oxygen generator, especially medical oxygen generator,CAN GAS recommends to choose a brand with long machine life, stable oxygen concentration, and low repair rate, so as to ensure the quality of medical oxygen,but also responsible for the patient.
