The Pressure Swing Adsorption (PSA) Oxygen Generator represents the pinnacle of advanced gas separation technology, offering a reliable and efficient solution for onsite oxygen production. Leveraging the power of high-quality zeolite molecular sieves as the adsorbent, our PSA systems separate oxygen from compressed air to deliver purity levels up to 95%, effectively replacing traditional bottled oxygen supply.
Key Features & Advantages:
- Adaptive Purity Control: The product purity can be modulated according to changes in flow demand, providing flexibility for various industrial and medical applications.
- Safety & Energy Efficiency: Operating at medium to low pressures, the PSA technology ensures a safe working environment while minimizing energy consumption.
- Ease of Operation & Maintenance: Equipped with touchscreen control panels, these units offer fully automated operation, requiring minimal supervision and facilitating easy maintenance procedures.
- Customizable Solutions: Tailored for different sectors such as chemical, petroleum, food industries, and more, the 10 cubic meter PSA Oxygen Generator weighs 950kg and boasts a processing capacity of up to 100 cubic meters per hour, delivering oxygen with a purity not less than 93% and an oxygen dew point below -40°C.
Working Principle: The PSA process involves the selective adsorption of nitrogen from compressed air onto the surface of the molecular sieve, leaving behind a concentrated stream of oxygen. The adsorption and desorption cycles occur alternately under controlled pressure swings to ensure continuous and consistent oxygen output.
Applications Overview: From critical emergency medical oxygen supplies to supporting large-scale industrial processes that require a steady flow of pure oxygen, PSA Oxygen Generators are designed to meet diverse needs. They play a pivotal role in alleviating hypoxia symptoms in patients, serving as a cornerstone in clinical treatments for pathologically-induced oxygen deficiencies, and contributing to environmental sustainability through their energy-efficient and cost-effective design.
Technical Specifications: Powered by either 380V/220V, 50/60Hz electrical supply, our PSA units operate with a noise level not exceeding 75dB(A) and boast a stable output pressure of ≥0.3Mpa. With twin vessels filled with specialized ZMS, they ensure continuous and efficient oxygen generation without compromising on performance or reliability.
Innovation and Comparison: Compared to VPSA (Vacuum Pressure Swing Adsorption) systems, PSA technology is particularly well-suited for smaller to medium-sized oxygen production requirements, offering a robust balance between capital investment, operating costs, and overall efficiency.
Invest in PSA Oxygen Generators for a sustainable and dependable oxygen supply solution that delivers optimal performance and unparalleled value across multiple industries.
Product Description
Pressure swing adsorption oxygen production is to use zeolite molecular sieve as adsorbent, using the principle of pressure adsorption and pressure desorption to adsorb and release nitrogen from the air, so as to separate oxygen. Zeolite molecular sieve is a kind of spherical granular adsorbent which is processed by special pore type treatment process, and its surface and interior are full of micropores. The characteristics of its pore make it possible to realize the kinetic separation of O2 and N2. The separation of O2 and N2 by zeolites is based on the small difference of the kinetic diameters of the two gases. N2 has a faster diffusion rate in the micropores of zeolites, while O2 has a slower diffusion rate. The diffusion of water and CO2 in compressed air is similar to that of nitrogen. Finally, oxygen molecules are enriched from the adsorption tower.
Oxygen generators produce gaseous oxygen from compressed air on site and offer a cost-effective, reliable and safe alternative to traditional oxygen gas supplies such as cylinders or cryogenic liquid. Oxywise Oxygen Generators are available in 40 standard models with capacity ranging from 1 to 200 Nm3/hour at 90-99% purity. The design is made for round the clock 24/7 operation. Each generator is equipped with automatic start&stop function, enabling the generator to start and stop automatically according to the consumption.
Oxygen generator incorporated with oxygen high pressure compressor for filling cylinders creates a system called Oxygen generating and filling station. System consists of essentials such as air compressor, dryer, filtration etc. and standard features including molecular sieve protection, stainless steel piping and many more.

4,Compressed air pretreatment
Because the molecular sieve in the main oxygen generator has high requirements for the quality of compressed air, and the gas temperature in the compressed air is high, and it contains a lot of water, certain dust and oil mist, so before the compressed air enters the oxygen generator, it must be treated with water, oil and dust removal, and this part of the equipment is mainly for this purpose.
The purification of compressed air is very important, please do not ignore this point! Because the quality of compressed air purification treatment is directly related to the service life of molecular sieve, which is directly related to the long-term effective use of oxygen generator.
Adsorption dryer or freezing dryer are mainly used to remove water from compressed air.
Different types of multi-stage filters with different filtering accuracy are mainly used for oil, water and dust removal of compressed air. Generally speaking, for oil-free air compressors, one to two-stage filters are required, mainly for dust removal and water removal; for oil-bearing air compressors, three to four stage filters are required, mainly for oil removal, water removal and dust removal.
In high humidity environment, it is recommended to install special blowdown tank to filter a large amount of water vapor in compressed air.
