Nitrogen Generator By Pressure Swing Adsorption (PSA)
Nitrogen generator by pressure swing adsorption is the use of a carbon molecular sieve adsorbent processed from high quality coal, coconut shell or epoxy resin under pressurized conditions, the diffusion speed of oxygen and nitrogen in the air into the carbon molecular sieve hole, so as to separate the oxygen and nitrogen in the air. Compared with nitrogen molecules, oxygen molecules first diffuse into the holes of carbon molecular sieve adsorbent, and the nitrogen that does not diffuse into the holes of carbon molecular sieve adsorbent can be used as the product output of gas for users.

VPSA Oxygenerator
The VPSA Oxygen Generator is a pressurized adsorption and vacuum extraction oxygen generator. Air enters the adsorption bed after compression. A special molecular sieve selectively adsorbs nitrogen, carbon dioxide and water from the air. The molecular sieve is then desorbed under vacuum conditions, recycling high purity oxygen (90-93%). VPSA has a low energy consumption, which decreases with increasing plant size.
Shanghai LifenGas VPSA oxygen generators are available in a wide range of models. A single generator can produce 100-10,000 Nm³/h of oxygen with 80-93% purity. Shanghai LifenGas has extensive experience in the design and manufacture of radial adsorption columns, providing a solid foundation for large-scale plants. -
Oxygen Generator by Pressure Swing Adsorption (PSA)
According to the principle of pressure swing adsorption, the pressure swing adsorption oxygen generator uses the artificially synthesized high quality zeolite molecular sieve as the adsorbent, which is loaded into two adsorption columns, respectively, and adsorbs under pressure and desorbs under depressurized conditions, and the two adsorption columns are in the process of pressurised adsorption and depressurized desorption respectively, and the two adsorbers alternately adsorb and desorb, so as to continuously produce oxygen from the air and supply customers with oxygen of the required pressure and purity.
