Description: PSA-N2 variable pressure sorption air nitrogen making machine takes compressed air as its raw material. It utilizes different diffusion rate of O2 and N2 in air on carbon molecular sieve to separate O2 from N2.It gains N2 with more than 99%purity in the air.

Features: 1) Air nitrogen-making scale is shapeable.  It is of advanced technique, simple flow and sound safety.

         2)  It employs German imported BF molecular sieve and Japan (SMC) imported air-controlled valve with stable performance and high nitrogen purity. Our company’s HD model nitrogen-making equipment adopts micro-computer controller with easy operation. It start button may produce N2 with high purity. It may form a complete set for use with various automatic packing which requires N2 filled packing. It is of remarkable effects.
