Oxair Gases

ON-SITE OXYGEN PSA SYSTEMS

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 to Customer requirements when compared to conventional cryogenic equipment.

STANDARD PSA GENERATORS
Oxair Oxygen Systems eliminate the expense, inconvenience and hazards of handling and storage associated with purchased high-pressure oxygen. 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.
