The working principle of PSA nitrogen generator：

The raw material air is compressed by the air compressor and enters the post-stage air storage tank. Most of the oil, liquid water and dust adhere to the container wall and flow to the bottom of the tank and are regularly discharged from the blowdown valve. Part of it enters the compressed air purification system with the air flow.

The air purification system consists of a refrigerating machine, three filters with different precisions and a degreaser. The liquid water, oil, and dust in the compressed air are filtered clean by freezing and dehumidification and the filter from coarse to fine.
The dew point of the compressed air pressure is reduced to 2~10℃, the oil content is reduced to 0.001PPm, and the dust is filtered to 0.01μm, which ensures the cleanliness of the raw gas entering the PSA nitrogen generator.
The purified air enters the two adsorption towers of the nitrogen making machine through two paths, and is alternately adsorbed and desorbed through the automatic switching of the pneumatic valve on the nitrogen gas generator. This process separates most of the nitrogen and a small part of oxygen gas in the air.and evacuated the oxygen-enriched air. Nitrogen enriched at the top of the tower is transported to the back-stage nitrogen storage tank by pipeline, and enters the gas point after passing through the flow meter.
