The oxygen concentrator compresses air, which then passes through an air purification system to remove impurities such as oil, water, and dust,before entering an adsorption tower filled with zeolite molecules. Nitrogen,carbon dioxide, and water vapor in the air are largely adsorbed by the molecular sieve, while oxygen passes through the adsorbent due to its high diffusion rate, achieving the separation of oxygen and nitrogen.
