Because the nitrogen machine in the molecular sieve regeneration process, will be resolved before the adsorption of oxygen, this part of the gas pressure is not too high, and with the increase of the analysis time, the pressure is getting lower and lower, so in the discharge must pay attention to minimize the pressure loss of the pipeline on the air flow, to avoid the impact on the normal work of the nitrogen equipment.

On the other hand, the nitrogen machine to discharge a certain purity of oxygen is not beneficial to people and some equipment, and sometimes it will be harmful, to consider the emission to a safe, air circulation place. This is good for people and some equipment, and the placement site cannot be absolutely sealed.
