Supply pressure changes alter a manually balanced branch flow.
The sensor and modulating actuator adjust the blade to maintain the configured airflow.
The DN150 nominal unit uses the documented 152 mm actual inlet. An averaging probe senses inlet flow and feeds the actuator/controller, which positions a sealed double-skin blade inside the galvanized casing.
