Equipped with a special carbon molecular sieve adsorption tower a total of A, B two Nitrogen. When the clean air into the inlet tower A to the outlet by the carbon molecular sieve flow, O2, CO2 and H2O are the adsorption, the product nitrogen outlet flow from the absorption tower. After a period of time, A tower of carbon molecular sieve adsorption saturation. At this time, A tower automatically stop adsorption, oxygen and compressed air into the B tower production of nitrogen, and A tower on a molecular sieve regeneration. Regeneration of molecular sieve adsorption tower through the rapid removal of the adsorbed atmospheric pressure down to the O2, CO2 and H2O to achieve. Two alternating adsorption and regeneration tower, complete separation of oxygen and nitrogen, continuous output of nitrogen. The process by the programmable logic controller (PLC) to control. When the outlet end of the size of the set value purity nitrogen, PLC program effects, automatic venting valve opens, emptying the failure nitrogen automatically, to ensure that failure does not flow nitrogen gas point. Gas venting when the muffler so that noise is less than the use of 75dBA.

Compressed air components: Compressor, air tanks; Air cleaning parts: High degreasing, precision filter, compressed air dryers, air buffer tank, activated carbon filters; Nitrogen host part: Absorption tower, PLC controller, nitrogen, dust filter, nitrogen tanks, compressed air as a raw material and power, through the PSA system to take 95% purity 99.9995% nitrogen; Nitrogen purified components: The use of carbon-containing purification device (hydrogen purification unit) on the 99.9% of the common nitrogen to purify, to get high-purity nitrogen (99.999% 99.9995%).
