Working Principle

Under certain pressure, the difference of diffusion rate between nitrogen and oxygen in the air is quite different on carbon molecular sieve; oxygen molecule is absorbed largely by the carbon molecular sieve and nitrogen molecule concentrates in gas-phase in a short time, so as to realize separation of oxygen and nitrogen.

Due to that the absorption capacity of carbon molecular sieve for oxygen varies largely from different pressure, reducing the pressure can make the carbon molecular sieve release the absorbed oxygen molecule and regenerate the carbon molecular sieve, so as to realize repeated recycling of it.

It adopts the technique of two absorption towers, which one tower absorbs oxygen and produces nitrogen another tower releases the absorbed oxygen and regenerates the carbon molecular sieve. This cyclic-alternating pattern can produce high-quality nitrogen continuously
