In order to provide high purity nitrogen throughout the sprinkler system, the entrapped oxygenated air needs to be removed. The easiest way to remove that oxygen is to purge that system with nitrogen. In order to remove the oxygen, there must be a purge device installed at the far point of the system to allow it to escape. Potter has two options available that, combined with your Potter Nitrogen Generator, ensure your system is full of high purity nitrogen.
