Circular modulating fire damper RABCR

Bevent Rasch has developed a fire damper E60/E120-S with modulating actuator. This means the air flow can be adjusted with the damper blade angle 0-100% via input signal 2-10 V. It can also be used as adjustment damper or control damper and have a complete fire function at the same time.

Quick facts

  • Full protection against the spread of combustion gas
  • Sizes from 100 mm to 630 mm
  • Prefitted regulating safety actuator 24V
  • Installation in ducts
  • Easy regulation of flow
  • Available in MagiCAD
  • CE-marked building product according to 15650:2010


Damper in combination with walls or joist systems for fire separation of heating, ventilation and air conditioning installations in buildings. In accordance with the harmonised European standard EN 15650:2010. In designs according to associated documents, installation instructions and when the damper is used in combination with smoke detectors and monitoring system, the spread of combustion gases is prevented. No further action against the spread of combustion gases is required.


Modulating smoke dampers are delivered prepared for external insulation. The control signal can come from a room controller, air quality sensors, or other devices that provide 2-10V DC output. The actuator provides a feedback signal to 2-10V DC depending on throttle position. When power is lost the damper closes with actuator spring.
