Oxygen Concentrator

Oxiti Industrial Oxygen Concentrator

This device is intended to supply oxygen for applications requiring high concentration. It provides an enriched product gas by concentrating the oxygen contained in atmospheric air. The operation of the device begins with air being pulled into the external air intake filter.

The filtered air enters the compressor via a suction resonator and fine filter. Pressurised air then exits the compressor and into an electronic valve system that directs the air into one or two tubes that contain a molecular sieve (sieve beds). The molecular sieve adsorbs (physically attracts) the nitrogen from the air as it is pushed through the sieve beds. This allows the oxygen enriched product gas to pass through before being delivered to the process regulator.

As one tube is generating the product gas, the other is being purged of the purged nitrogen; this process is called pressure swing adsorption (PSA). After passing through the regulator, the rat of product gas delivery is set by the flow meter adjusting valve. Finally, it passes through a fin particle filter (product filter) and then exits the device through a fir-resistant outlet.

How it works

A high-quality compressor compresses over 100 litres of air per minute. The compressed air feeds into an air dryer to remove all the moisture and other impurities. After the air dryer the air flows into one of the two oxygen sieves. In the sieve nitrogen molecules stick to zeolite under pressure and oxygen passes through the sieve and flows to a small storage container. When the oxygen sieve saturates, and this happens in a matter of seconds, the solenoid valve system will switch to the second sieve to repeat the process. The first sieve than depressurizes and the nitrogen purges out of the sieve and the oxygen concentrator. This process is constantly repeated.
