Jiayu air separation equipment uses carbon molecular sieve as adsorbent to separate high-purity nitrogen and oxygen by using pressure swing adsorption principle to separate high-purity nitrogen and oxygen. The purity of nitrogen is up to 99.999%, which has high safety. Adapted to strong and continuous production, it is widely used in various industries. The equipment has compact structure, low operating cost, low energy consumption and high efficiency. The gas flow and purity can be adjusted according to actual needs. Jiayu is one of the earliest companies engaged in R&D and production of pressure swing adsorption high purity nitrogen generators in China. It mainly includes PSA nitrogen generator, PSA oxygen generator, stainless steel nitrogen generator, nitrogen purification device, etc. The products are exported to Europe and the United States.
