Description

Technical Parameters

The PSA Oxygen Generator is a highly efficient device that utilizes Pressure Swing Adsorption (PSA) technology to separate oxygen directly from air. Using high-quality molecular sieves, it selectively adsorbs nitrogen at ambient temperature and pressure, continuously delivering 90%–96% high-purity oxygen.

The PSA oxygen generator uses advanced pressure swing adsorption technology to extract oxygen from compressed air. The oxygen content in compressed air is about 21%, and nitrogen accounts for about 78%. When passing through the zeolite molecular sieve layer, the molecular sieve has a higher adsorption capacity for nitrogen and moisture, allowing the oxygen to be pressurized and output. During the adsorption process, one tower performs the adsorption operation, while the other tower is regenerated by decompression to release the adsorbed gas. This cycle is automatically controlled by a solid-state programmable controller to ensure that the process valves operate alternately and have automatic start and stop functions. Even during peak periods, the oxygen flow and purity can be kept stable. Under normal maintenance conditions, the service life of the zeolite molecular sieve can be almost infinite.

PSA Oxygen Generator work principle

NEWTEK produces high-end oxygen generators for you!

Air Compression and Purification

Air enters the purification system through a compressor, where dust, oil, and moisture are removed, ensuring clean, dry air enters the adsorption tower.

Adsorption Separation

The adsorption tower is filled with a high-efficiency molecular sieve (such as zeolite). Under pressure, the molecular sieve preferentially adsorbs nitrogen and some impurities in the air, while oxygen, due to its weaker adsorption capacity, is concentrated.

Oxygen Production

Unadsorbed oxygen is collected and transported to a buffer tank, maintaining a stable flow and pressure, and outputting high-purity oxygen at 90%–96%.

Desorption and Regeneration

When the adsorption tower reaches saturation, the system switches to a decompressed state, releasing the adsorbed nitrogen and impurities and regenerating the molecular sieve.

Dual-Tower Alternating Operation

PSA oxygen generators typically use two or more adsorption towers operating alternately to achieve a continuous and stable oxygen supply.

FAQ

1.What oxygen purity can a PSA Oxygen Generator provide?
PSA Oxygen Generators typically deliver oxygen with 90%–96% purity, meeting both medical standards (93% ±3%) and various industrial requirements.

2.How long does it take for the generator to start producing oxygen?
The system is designed for quick start-up and can produce oxygen within 10–15 minutes after being switched on.

3.What are the main advantages compared to oxygen cylinders or liquid oxygen?
PSA Oxygen Generators provide on-site, continuous oxygen supply, reduce transportation and refilling costs, enhance safety by avoiding liquid oxygen storage, and are more reliable for 24/7 operations.

4.What industries can use PSA Oxygen Generators?
They are widely used in hospitals and clinics, metallurgy, glass manufacturing, chemical processing, aquaculture, and wastewater treatment.

5.How to select the right PSA Oxygen Generator model?
Selection depends on oxygen purity requirements, flow rate (Nm³/h), pressure level, and application field. A professional supplier can design a customized solution tailored to your needs.
