What is medical oxygen concentrator

Currently all medical oxygen generators use the world's advanced PSA (Pressure Swing Adsorption) air separation oxygen technology, which is based on the attractant (zeolite molecular sieve) on the difference between the oxygen and nitrogen adsorption capacity in the air to realize the separation of oxygen and nitrogen. When the air enters the bed equipped with the adsorbent, the nitrogen adsorption capacity is stronger to be adsorbed, while the oxygen is not adsorbed, so that a high concentration of oxygen can be obtained at the exit end of the adsorbent bed. Because the adsorbent has its adsorption amount with the pressure change characteristics, change its pressure, can make the adsorption alternately adsorption and desorption operation.
