When the set point is attained, the Humex deactivates the high flow (as well as the Humex humidification system) to

conserve on nitrogen. In this low-flow purge, the flow rate is restricted by the Dual Purge flowmeter.

Refer to Operating Manual No. 1800-42 or 1800-13 for further information on Terra’s Glove Box Dual Purge System.
