Air contains 21% Oxygen, 78% Nitrogen, 0.9% Argon and 0.1% other trace gases. Oxair Oxygen generation systems separate this oxygen from Compressed Air through a unique process called Pressure Swing Adsorption. (PSA). 

The Pressure Swing Adsorption process for the generation of enriched oxygen gas from ambient air utilises the ability of a synthetic Zeolite Molecular Sieve to absorb mainly nitrogen. While nitrogen concentrates in the pore system of the Zeolite, Oxygen Gas is produced as a product.

Oxair Oxygen generation plants use two vessels filled with Zeolite Molecular sieve as adsorbers. As Compressed Air passes up through one of the adsorbers, the molecular sieve selectively adsorbs the Nitrogen. This then allows the remaining Oxygen to pass on up through the adsorber and exit as a product gas.

When the adsorber becomes saturated with Nitrogen the inlet airflow is switched to the second adsorber. The first adsorber is regenerated by desorbing nitrogen through depressurisation and purging it with some of the product oxygen. The cycle is then repeated and the pressure is continually swinging between a higher level at adsorption (Production), and a lower level at desorption (Regeneration).

Why Oxair PSA Oxygen?

The main advantages of using Oxair PSA Oxygen when compared to conventional cylinder or liquid supply.

Standard PSA generators

Oxair Oxygen Systems eliminate the expense, inconvenience and hazards of handling and storage associated with purchased high-pressure oxygen cylinders. Oxair offers a very wide range of models that are efficient and reliable. Systems are fully automatic and do not require any specialised operating personal or training. Simply connect an air compressor or shop air supply to the generator and your oxygen distribution system to the oxygen receiver outlet. Once the power is connected, turn the unit on and set the delivery pressure. The simple on/off switch supplies oxygen whenever you need it. System will go into standby mode when oxygen is no longer required.

Supplying Diverse Applications

As a world provider of Oxygen PSA Systems Oxair supplies equipment from the simplest to the most sophisticated control systems for the petrochemical and Oxidisation Processes. Whether at an Aquaculture, Water Treatment facility or small brazing application The Oxair name symbolises Diversity and quality.

Oxair Gas Systems excel as a leading supplier of PSA Oxygen Systems Worldwide Offering the most cost-effective, most efficient and safest oxygen sources for today’s diverse oxygen applications

Small Cabinet Series

The Cabinet Series are designed for continual operation 24 hours per day, 7 days per week.  All valves and control equipment are contained in the front cabinet.  With the air and oxygen receivers mounted on the same skid as the PSA oxygen generator (2 skids in larger models), the system is pre-wired and pre-piped, ready to go.

Process Series

The Process Series are designed for medium to high oxygen flows and unattended operation. The process has optimised bed sizings for reduced power consumption. Some clients install two process series generators rather than a single Tonnage system.

Tonnage Series

The Tonnage Series are designed for applications requiring large amounts of oxygen, or to replace bulk liquid oxygen storage vessels.  Plants can be designed for outdoor or covered (standard) installations.

Medical Oxygen Series

Oxair Medical Oxygen Systems are designed to supply an extremely reliable and continuous flow of Oxygen delivering a constant on-line oxygen purity and pressure.

All Oxygen PSA Systems are monitored to ensure an uninterrupted supply of medical-grade oxygen. Oxair Gas Systems can custom design a system to the customer’s requirements as well as design a system to cater for peak demands.

Alarm systems can include, automatic switching over to secondary back up system, cylinders, or liquid back up system.
