Oxygen is one of the most widely used gases in hospitals and medical centers and its main use is for breathing and resuscitation of patients as well as in anesthesia machines. Oxygen supply in hospitals is very important as the most vital medical gas for patients. Therefore, the supply source of this gas must be reliable, economical, safe and stable. Hospital oxygen generator systems are known as one of the most reliable sources of supply in hospitals due to the structure of oxygen gas production from air. Pressure Swing Adsorption (PSA) oxygen generators separate oxygen from air and produce high purity oxygen. The devices manufactured by Vala Darman Amirkabir Company are designed and manufactured according to the Iranian national standard 10766 and the international standard 10083 and have a production license from the Ministry of Health, Treatment and Medical Education.

One of the important components of the hospital oxygen generator is the air compressor of the device. Considering the 24-hour operation of this device in hospitals, it should be of very high quality. This company has always tried to use world-class compressors in the construction of this device.

Briefly about the Pressure Swing Adsorption method

Air consists of 21% oxygen, 78% nitrogen and 0.1% other gases. The device separates oxygen from compressed air through a unique process called molecular absorption under pressure. In this production process, a material called molecular sieve (synthetic zeolite) is used, which extracts nitrogen from compressed air under pressure. high, absorbs and releases with low pressure. This device uses two tanks filled with zeolite as absorbent to perform this operation. When the compressed air enters one of the generating tanks, the molecular material absorbs the nitrogen. At this moment, the remaining oxygen comes out from the other side of the tank and through the transmission pipe. Before the absorbent material is completely saturated with nitrogen, the compressed air is directed to the other tank. At this moment, in the second tank, like what happened before, nitrogen absorption starts again through pressure reduction and the process of oxygen removal starts. This cycle, which is repeated, continues until it provides the final oxygen with 90% purity. If stored in proper conditions, the molecular save material is always regenerated and does not need to be replaced.
