CFDM fire dampers are diaphragms in ducted ventilation systems that prevent the spread of fire and products of combustion from one fire segment to another by closing the air duct at points of fire separation structures. The damper diaphragm automatically closes the air duct with a closing spring.

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.
