PSA oxygen generator functioning principle

PSA oxygen generator is determined by PSA, applying higher high quality of zeolite molecular sieve as absorbent, under pressure from some, preparation of oxygen in the air. Right after purification and drying of compressed air, pressurized within the adsorber adsorption and vacuum desorption.
PSA Oxygen Generator
Resulting from the aerodynamic effects, nitrogen in zeolite pore diffusion rate far higher than oxygen, nitrogen preferential adsorption by zeolite molecular sieve oxygen in the gas phase is enriched, oxygen into the final solution.

Then after decompression to atmospheric stress, impurities for example nitrogen adsorption by sorbents desorption, reaching regeneration. Basic settings in the method of two adsorbers, a tower adsorption oxygen-producing, desorption and regeneration of an additional Tower, controlled by PLC system controller of pneumatic valve opening and closing, to ensure that the two cycles to be able to attain the objective in the continuous production of high-quality oxygen.
VPSA Oxygen Generator
The entire program consists of the following elements: compressed air purification units, air tank, oxygen-nitrogen separation device, oxygen buffer tank if desired filling cylinders, end with oxygen booster compressor and filling device.
