Principle of oxygen making by oxygen making machine Now most manufacturers adopt molecular sieve technology, and the oxygen concentration is stable, ensuring the demand of oxygen inhalers to the greatest extent.

In addition to oxygen cylinders, the oxygen production principles of other oxygen generators can be roughly divided into four categories; 1, molecular sieve oxygen generator, which uses the principle of pressure swing adsorption to separate medical pure oxygen from air; 2. Electrochemical oxygen generator, which generates oxygen by adding chemicals (such as early Morino machine, winning numbering machine, oxygen station); 3. Membrane oxygen generator, which uses the different diffusion rates of oxygen and nitrogen in the air through the oxygen-enriched membrane to generate oxygen-enriched air (such as Haiyao Home Oxygen Generator); 4. Chemical oxygen generator, which uses chemical reagents to generate oxygen (such as oxygen).

If the oxygen concentration reaches the standard and the use cost is low, you can choose a molecular sieve oxygen generator (such as Song Xin).

Now molecular sieve oxygen generator is the most common one in the market. The so-called molecular sieve is a natural or synthetic zeolite crystalline aluminosilicate with microporous cubic lattice. It is called "molecular sieve" because it absorbs or repels molecules of different substances according to the size of holes in its crystals. Molecular sieve has a porous skeleton structure, in which there are many pores with uniform pore size and holes with neat arrangement and large internal surface area. These crystals can only allow molecules with a diameter smaller than the pore size to enter the pores and be adsorbed, otherwise they will be rejected. Therefore, molecules with different sizes can be separated to play the role of screening molecules.
