Oxygen generators are used to produce high-purity oxygen for a variety of purposes. Oxygen generators can be used in hospitals and clinics, glass manufacturing industries, aquaculture, and more. O2 generators use pressure swing adsorption technology to pull oxygen from the surrounding air, and compared to methods of oxygen delivery, oxygen generators are eco-friendly, efficient, and reliable.

In this article, we&#;ll talk about the importance of PSA oxygen generator technology and how PSA oxygen gas generators use pressure swing adsorption to produce oxygen. If you work in an industry that requires a steady stream of oxygen, a PSA oxygen generator may be exactly what you need.
Pressure swing adsorption technology is used in gas generation because it is efficient and effective. The system is called pressure swing adsorption because it happens under pressure and swings back and forth between two vessels. As one vessel is being pressurized, another is depressurized. The system uses adsorption to separate oxygen from the air and produce a steady, high-purity stream of oxygen.
During the adsorption phase, the generator uses a zeolite sieve to retain nitrogen and send oxygen to a collecting tank. When the zeolite sieve has adsorbed all the nitrogen it can hold, the generator enters a desorption phase, during which time the cylinder is depressurized and the nitrogen is released.
Oxygen PSA generator technology includes adsorption columns, zeolite molecular sieves, and valve and control systems that help monitor the generator to ensure that it&#;s functioning properly.
Zeolite is a highly porous material that can be found in nature or created synthetically. Zeolite is very effective at adsorbing nitrogen, which makes it a very important part of your oxygen generator.
As pressure builds in the PSA system for oxygen, nitrogen is adsorbed into the zeolite sieve. It is this building pressure that leads to adsorption. When the pressure is decreased, the nitrogen is released from the sieve and can be ejected into the air.
There are many advantages of PSA generator oxygen systems. Pressure swing adsorption oxygen generators:
PSA oxygen generators are useful in a variety of industries, including:

PSA technology makes oxygen generation easy and cost-effective for businesses in a variety of industries. Compared to oxygen cylinders, which must be delivered regularly on trucks that require fossil fuels, pressure swing adsorption oxygen generator systems are better for the environment.
PSA technology produces a reliable, steady, high-purity stream of oxygen, and can be used in a variety of industries. In addition, a PSA system for oxygen generation incurs low operating costs compared to oxygen delivery.
If you&#;re in the healthcare industry, aquaculture, glass manufacturing, or one of the other industries mentioned above, you can benefit from a PSA O2 generator from On Site Gas Systems. Call today to discuss your oxygen needs and find out more about PSA oxygen generators.
GENERON® Oxygen PSA Generators separates oxygen (O2) from compressed air utilizing pressure swing adsorption technology. Compressed air, which consists of approximately 21% oxygen and 78% nitrogen, is passed through a bed of zeolite molecular sieve (ZMS). The sieve preferentially adsorbs N2 and moisture over O2 allowing the O2 to pass through as a product gas at pressure. While one of the towers is in the adsorption phase the other tower is regenerated by de-pressurizing, at which time the sieve releases the adsorbed gases to the atmosphere, and the cycle is then repeated. A solid state programmable controller operates the process valves on an alternating cycle, with built-in logic for automatic stop/start. Oxygen flow and purity remain constant regardless of the peak usage demands. Under normal operating conditions and with correct maintenance the zeolite molecular sieve will have an almost indefinite lifetime.
The PSA Oxygen Generator works the same as our Nitrogen PSA Generators with one exception. The adsorption media inside the vessel for an Oxygen PSA is a material called a Zeolite, for a Nitrogen PSA the material is called CMS (Carbon Molecular Sieve). In both cases compressed air is fed into one of the absorption towers. In the case of an Oxygen generator the Nitrogen in the Air is absorbed onto the Zeolite surface and the Oxygen passes out of the vessel at the desired purity. Once the Zeolite absorption material become saturated with Nitrogen the compressed air is switched to the other vessel which now does the absorption while the other vessel is regenerated.
The Zeolite material have a very unique property that when the pressure is released back to atmospheric pressure during the regeneration process the Zeolite releases the Nitrogen that was stored on its surface. The process consists of switching the compressed air from one vessel to the other by means of a series of valves in a very precise sequence to take advantage of this unique property.
This process provides a constant flow of Oxygen for a multitude of applications.
