Customized VPSA Oxygen Generator with 1-10 bar Pressure Range and 1 Year Warranty for Industrial Use

The VPSA Oxygen Generator is an efficient gas separation device that uses air as raw material and relies on the strong adsorption capacity of lithium-based or zeolite molecular sieves for nitrogen. It completes adsorption operations under low-pressure environment and achieves deep regeneration of molecular sieves through vacuum pumps, cyclically producing high-purity oxygen. Its modular design supports flexible capacity expansion with low maintenance cost, making it ideal for large-scale continuous oxygen supply applications.

The VPSA Oxygen Generator (Vacuum Pressure Swing Adsorption Oxygen Generator) realizes air separation based on the selective adsorption characteristics of molecular sieves, with a complete working cycle typically ranging from 60 to 90 seconds. In the adsorption phase, the blower delivers filtered compressed air (after removing oil, water, and dust through pre-treatment equipment) into the adsorption tower at a pressure of 0.1-0.3MPa (near atmospheric pressure). The tower is filled with lithium-based or zeolite molecular sieves, which have a 4-5 times stronger adsorption capacity for nitrogen than oxygen.

As air flows through the molecular sieve bed (with a height of 1.5-2.5 meters), nitrogen molecules are trapped in the sieve's porous structure, while oxygen (accounting for 21% of air) passes through unimpeded. The oxygen is then collected through the top outlet of the tower, and after being stabilized by a buffer tank, it is delivered to the user terminal with a purity of 90%-95%--a range that meets most industrial and medical standards.
