The Oxygen Concentrator, commonly known as the Variable Pressure Adsorption (VPA) Oxygen Concentrator, uses VPA technology to produce oxygen, which can be extracted from the air. The Oxygen Concentrator is filled with molecular sieves with a surface area of 800-1000 m2/g per gram. Under pressure, the nitrogen is adsorbed from the air using the physical adsorption and desorption techniques of the molecular sieves, and the oxygen that is not adsorbed is collected and purified to obtain oxygen of relatively high purity is obtained. When the molecular sieve is depressurized, the previously adsorbed nitrogen is re-emitted into the air. When pressurized again, the nitrogen is adsorbed again for oxygen production, thus the Oxygen Concentrator can produce oxygen in a cyclic and dynamic process.

Principle of the Oxygen Concentrator
Types
The key technology used in the Oxygen Concentrator is the variable pressure adsorption (VPS) technology, which extracts oxygen from the air. The molecular sieve is filled in the Oxygen Concentrator, usually with a surface area of 800 to 1,000 m2 /g, and the nitrogen is adsorbed in the air under pressure using the molecular sieve logistics adsorption technology and analysis technology. The purification function is used to process the collected oxygen high-purity oxygen. The previously adsorbed nitrogen is then discharged back into the air under reduced pressure. The nitrogen can then be adsorbed and pressurized again for oxygen production. Medical oxygen generators can produce oxygen on a cyclic basis, and the oxygen production process is a continuous, ever-changing process. The purification of the compressed air is accomplished with an air purification desiccant and finally, the air enters the adsorption tower through a switching valve. The molecular sieve adsorbs the nitrogen, and in the adsorption tower, the oxygen collects once again and is finally pushed into the oxygen storage tank. After removing the odor, dust, and bacteria from the oxygen, the final product is highly concentrated, clean medical oxygen with a concentration of 96%. The entire process is chemically neutral and therefore does not pollute the environment.
Molecular Sieve Oxygen Concentrator (VPS Oxygen Concentrator)
The Molecular Sieve Oxygen Concentrator is an advanced gas separation technology. It uses the physical method (PSA method) to extract oxygen directly from the air, which is ready to use, fresh, and natural, and the maximum pressure of oxygen production is 0.2~0.3MPa (i.e. 2~3kg), there is no danger of high pressure and explosion.
Chemical Oxygen Concentrator
Chemical Oxygen Concentrator is a reasonable pharmaceutical formula for use in specific situations. It can indeed meet the urgent needs of some consumers.
Electronic Oxygen Concentrator
The electronic Oxygen Concentrator is more common in pharmacies and uses a process of oxidation and reduction of oxygen from the air in solution, thus not producing dangerous hydrogen gas like the electrolysis of water to produce oxygen, and the whole machine is relatively quiet. However, the handling and use of these products are very strict, never allowing tilting and inverting, otherwise, the solution will flow into the oxygen delivery tube and spray into the nasal cavity, causing serious damage to the user. At the same time, the use of the oxygen production process is easy to produce other oxides, the oxygen produced contains chemical substances, and this type of oxygen production method consumes more electricity, according to experts. Now the world's best electronic Oxygen Concentrator service life is difficult to exceed 1000 hours, in the use of the process must ensure that the solution has the right concentration, otherwise can not be normal oxygen, choose the electronic Oxygen Concentrator customer maintenance work must be done.
