Circular fire damper RABR-VAP

Bevent Rasch has developed a fire damper for fire resistance classes E60S / E90S / E120S which is also used for constant pressure retention in all types of ventilation plants whilst providing full protection against the spread of smoke.

Use

Damper in combination with walls or joists for fire-sectioning of heating, ventilation and air conditioning installations in buildings. 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.

As the damper also functions as a constant pressure retention damper, both these functions are combined in the same damper. This saves both time, space and money for installations in, for example, hotels, office and shopping complexes, where both these functions need to be solved.

Design

RABR-VAP is supplied complete with a factory mounted, maintenance-free, 24 V electric safety actuator with thermal sensor featuring built-in signal contacts to indicate the damper position. RABR-VAP is supplied prepared for possible overinsulation of 50 mm. RABR-VAP is supplied calibrated from the factory. Nominal pressure is 100 Pa or 300 Pa depending on the pressure sensor’s range of measurement. Desired reference values are set using the regulator’s potentiometer between 30-100% of nominal pressure. The reference value can be remotely set with a 2-10V signal from the DUC, for example. The device can be force-controlled to different operational requirements. In case of of a power failure, the damper closes with actuator spring return.
