The central oxygen supply system consists of oxygen source, decompression device, safety alarm device, oxygen monitoring device, pipeline and terminal devices.

Oxygen source 1: Liquid oxygen tank

Safe, reliable, and easy to maintain.

Oxygen source 2: Oxygen generator

Based on the advanced PSA（Pressure Swing Adsorption）Technology, PSA Oxygen Generator uses molecular sieve as sorbent to produce oxygen with a purity of 93%±3 , which is suitable for medical use.

Oxygen source 3: Oxygen manifold

Two (or more than two) groups of oxygen cylinders make it possible to ensure alternate supply of oxygen by way of automatic or manual switchover.
