The RDR flow regulator is a component that is installed inside a duct to achieve a constant flow rate in a pressure range between 50 and 250 Pa. It is used in ventilation and air-conditioning systems, in the extract or supply air.
The RDR volume flow controller can be adjusted during installation to a given volume flow. The RDR controller has graduations on the sides of the opening to illustrate the level of adjustment.
