Important features • The Strulik BCF-K90 damper ideally combines the function of an infinitely variable supply and exhaust air valve with the fully effective properties of a damper having a K90 resistance class. • The damper is mounted directly into the fire-protected zone. Thus the disk valve itself guarantees the effectiveness of fire protection. • No special fixing arrangements are required (i.e. saving of time and high economy). • Strulik dampers may even be mounted subsequently into ventilation systems, in order to meet the effective fire prevention requirements. Essential features 1/ Safety classification. • Official classification: Resistance class K90 • Activation starting at 72 °C • Maximum sealing between the insulating material (flame tightness) • Flame stability 2/ Low noise level • Ideal aerodynamic characteristics • Maximum insulation The Strulik BCF-K90 dampers have been submitted to many test series in Germany and abroad. These test series did not only include the effectiveness of FIRE PROTECTION and FLAME TIGHTNESS, but also the STABILITY OF FLAMES and the correct functioning of the FUSIBLE LINK (see additional test certificate from the "Verband der Sachversicherer" in Cologne). In Germany the damper has been tested against fire and smoke in accordance with the principles of construction and testing of the "Deutsches Institut für Bautechnik" in Berlin. The expert opinion for a K90 resistance class has been prepared by the "Institut für Haustechnik" of the Technical University of Munich. VdS in Cologne has prepared the test report on the release mechanism for an activation temperature of 72 °C in accordance with DIN 4102. • The damper is fully integrated within disk valve and therefore does interfere with the through-flow of (ideal balancing ratio between volume and noise level). 3/ Adjustment of air volume • Infinitely variable control of al
