Rectangular regulating fire damper BSK6R

Bevent Rasch has developed a fire damper, fire class EI60 / EI60S with regulating actuator. This means it is possible to regulate the air flow from 0-100% with a control signal 2-10V, use it as an adjustment damper or boosting damper while providing complete protection against the spread of combustion gases.

Dampers in combination with walls or joists for fire-sectioning of heating, ventilation and air conditioning installations in buildings. In accordance with the harmonised European Standard EN 15650:2010. Smoke spread is prevented when the damper system design in accordance with the associated documentation, assembly and fitting instructions is used in combination with smoke detectors and the MRB (or equivalent) monitoring system. No further measures against the spread of smoke are required.


The regulating fire damper is supplied prepared for external insulation. The control signal can come from e.g. room controllers, air quality sensors, or other devices that give a 2-10V DC output signal. The actuator provides an actual value signal of 2-10V DC depending on the damper position. In the event of a power failure, the damper closes with the actuator’s spring.
