What is a PSA oxygen generator?
The primary use of oxygen is to supply respiration and support combustion; it is widely used in metallurgy, chemical, biochemical, medical, aviation, electronics, military, and scientific research, especially in the medical world. Recently, some people have called oxygen “medicine,” especially the new crown epidemic, which plays a significant role. The PSA oxygen concentrator is easy to operate, with little input, and the hospital can generate its oxygen for clinical use.

1. PSA OXYGEN Generator meaning
Pressure swing adsorption air separation oxygen production could be a new technology to supply oxygen from the air. Pressure swing adsorption (PRESSURE SWING ADSORPTION, PSA for short) may be a physical process approximating isothermal changes. It uses the adsorption capacities of various components within the gas medium on the adsorbent. Therefore, the adsorbent selects when the pressure increases—adsorption, desorption, and regeneration when the pressure is reduced. Pressure swing adsorption air separation oxygen production generally uses two adsorption towers; the towers are full of zeolite molecular sieve adsorbent. When one adsorption tower absorbs nitrogen and produces oxygen, the opposite adsorption tower removes nitrogen and regenerates so that oxygen is continuously produced in an alternating cycle.
2. How does PSA oxygen work？
Normal air contains 21% oxygen and 78% nitrogen. An oxygen generator produces oxygen from the air, separates the rest of the gas, and exhausts it into the air.
The Variable Pressure Adsorption oxygen generator uses 5A zeolite molecular sieves as adsorbents to separate oxygen and nitrogen in the air due to the different adsorption properties of molecular sieves for nitrogen and oxygen. Thus, selective adsorption of oxygen in the air. The atmosphere is compressed and then coated with an air purification system to remove impurities such as oil, water, and fixed dust and then enters the adsorption tower equipped with zeolite molecular sieves, where nitrogen, carbon dioxide, and water are adsorbed by the molecular sieves in large quantities. Oxygen is separated through the adsorbent due to the significant diffusion rate.

What is a PSA oxygen generator?
Air contains 21% oxygen, 78% nitrogen, 0.9% argon, and 0.1% other trace gases.
PSA oxygen generator uses a zeolite molecular sieve as an adsorbent. Use two containers with zeolite molecular sieves (two towers, four towers, or six towers) as adsorbents, using the principle of pressure adsorption and decompression desorption to adsorb and release oxygen from the air, thereby separating the oxygen from the automatic equipment. A zeolite molecular sieve is a spherical granular adsorbent with micropores on the surface and inside. It is processed by a unique pore-type treatment process and is white. Its pore-type characteristics enable it to realize the kinetic separation of O2 and N2. The separation of O2 and N2 by zeolite molecular sieve is based on the slight difference in the dynamic diameter of these two gases. N2 molecules have a faster diffusion rate in the micropores of the zeolite molecular sieve, and O2 molecules have a slower diffusion rate. The diffusion of water and CO2 in compressed air differs significantly from that of nitrogen. The final enrichment from the adsorption tower is oxygen molecules. The pressure swing adsorption oxygen production is based on the selective adsorption characteristics of the zeolite molecular sieve. It adopts the cycle of pressure adsorption and decompression desorption to make compressed air alternately enter the adsorption tower to achieve air separation, thereby continuously producing high-purity product oxygen.
What is An oxygen generation system?
An oxygen generation system is a device that produces oxygen from ambient air. It works by separating oxygen from other gases in the air, such as nitrogen and argon, using pressure swing adsorption (PSA). PSA passes compressed air through a bed of adsorbent material, which selectively adsorbs nitrogen and other gases, allowing oxygen to pass through. The oxygen is then collected and stored in a tank for various applications, such as medical facilities, industrial processes, and aerospace.
