how does PSA work

PSA( Pressure Swing Adsorption) is an advanced gas separation technology, based on the physical adsorption of the internal surface in the adsorbent to gas molecules, separating the gas by the characteristics of absorbing to the quantity of different gas in general pressure. The CMS (Carbon Molecular Sieve) is a sorbent picked up from the air, used in separating Oxygen and Nitrogen molecular. The absorption quantity of CMS is greatly higher for Oxygen than Nitrogen under the same pressure.


Low Operating cost; Automatic operation; Produces oxygen from compressed air; easy to install and maintain.

Oxygen concentrator QA

1. What is the difference between a VPSA oxygen concentrator and a PSA oxygen concentrator?

The PSA oxygen concentrator is suitable for use under 300 cubic meters and has the characteristics of simple and convenient, movable.

VPSA oxygen concentrator is suitable for more than 300 cubic meters of use, the greater the gas volume, the lower the energy consumption.

2. What is the difference between a fish pond aerator and a fish pond oxygen concentrator?

The aerator is a self-contained air pump that mixes 20% of the oxygen in the air into the water.

The oxygen concentrator is dissolved in water by producing 90% pure oxygen.

Merchants need to consider the choice of aerobics or oxygen concentrators based on the type of fry, increasing the oxygen production rate to increase the production cycle, and the total ratio of fish ponds.

3. What is the purity of the PSA oxygen concentrator?

The purity of the general PSA oxygen concentrator is 90%-93%.

Our company’s PSA oxygen concentrator can reach 95%, 98%, up to 99.999.

4. What should I pay attention to when using the oxygen concentrator for ozone?

Ozone supporting oxygen concentrators mainly need to select an oxygen concentrator with stable gas volume and purity to avoid ozone concentration and production due to instability.

5. How to maintain the PSA oxygen concentrator

The daily maintenance of the oxygen concentrator is relatively simple:

 (1) Open the air storage tank drain once a day and drain the condensate from the air.

(2) Check the automatic drainer daily to avoid clogging and lose drainage. If it is blocked, open the manual valve slightly, close the self-discharge valve and then remove the automatic drainer to disassemble and clean. When cleaning the automatic drain, use soap to clean.

(3) The oxygen concentrator mainly checks the working pressure of the adsorption tower, and records the purity and flow rate.
