PSA (Pressure Swing Adsorption) technology, which is deffirent from traditional cryogenic technology, is going to more and more popular used for air separating. Each gas has a specific adsorption rate when they pass through the vessel filled with molecular sieves (Zeolite molecular sieves) under a swing pressure. Most of Nitrogen molecules are trapped by ZMS, and other gases(Oxygen gas) are collected out for production gas.

Suitable for:
Healthcare, breath-grade oxygen supply for home & office, so on.
