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.
BR-S1/010 potentiometer
Potentiometer designed to set the desired speed value for fans equipped with electronically commutated EC motors. The potentiometer requires a power source max 10-12V DC / 1mA, which is available from the EC fans. The output is a stepless 0-10 V DC signal. Resistance 10 kΏ.

CSR-B EC W, CSR-B EC Zero Plus W, CSR-B EC NFC W controller
Controllers of the CSR-B series are constant pressure regulators designed for cooperation with duct and roof fans with EC motors. By continuously controlling the fan speed, they ensure constant pressure in the ventilation ducting. Based on a PI controller, CSR-B controllers have the option to set a constant fan power and programmable upper and lower fan control limits.
