Round constant volume flow control - 125mm - Airflow 50 m3/h - RDR 125 15 50
The adjustable control module ensures a constant flow, regardless of aeraulic fluctuations in your ventilation system. It stabilises the flow rates in your mechanical ventilation or climate control system. The module has one lip seal for a good seal in the system. The control module is easy to set to your desired constant air flow. The air supply is adjustable and can be read from the side of the regulator. The control membrane expands and retracts according to the pressure difference between the front and back of the module, thus changing the air passage. The module can be used up to a maximum temperature of 60°C.
The module is easy to install in a round ventilation pipe near a branch or an end piece.
