Pressure swing adsorption nitrogen generator (nitrogen generator, nitrogen generator) uses compressed air as raw material, and uses carbon molecular sieve high-performance sorbent to selectively adsorb oxygen and nitrogen to directly produce nitrogen. Under the action of pressure swing adsorption, the purified compressed air is subjected to pressure adsorption and decompression desorption. Due to the kinetic effect, the diffusion rate of oxygen molecules with smaller kinetic diameters in the carbon molecular sieve micropores is much higher than that of nitrogen molecules. Before the adsorption reaches equilibrium, nitrogen is enriched in the gas phase, and the product nitrogen is obtained. Then, by reducing the pressure to normal pressure, the adsorbed nitrogen and other impurity components are desorbed, and the regeneration of the carbon molecular sieve is realized.

The first choice of pressure swing adsorption nitrogen generator needs to know the parameters: flow-purity-pressure. Knowing these three aspects, you will know how to choose a nitrogen generator.
