Accessories (optional): MS-C - electrical limit switch VMT - disk valve for overflow opening NW 100/125/160 or 200 Mounting frame for installation into: Resistance class K90/K30 in accordance with DIN 4102-6 - light partitions, brickwork or concrete floors - as above, however lengthened, L = 140 mm - F30/F90 supplement floors, shaft walls or classified ducts, L = 140 mm - as above, however in short version for a floor thickness ≤ 30 mm - solid walls (dry mounting) - massive floors and supplement floors (dry mounting) - light partition walls (dry mounting) For the installation into a F30 supplement floor. If the mounting frame and floor thickness have not been specified, the KKL-ZX will be delivered with loose angles for fastening) Important features • The Strulik BCF-2-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 • Maximum sealing 2/ Low noise level • Ideal aerodynamic characteristics • Maximum insulation • 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). Please note: For examples of application, see BTZ-2 on page 111 - 115, 117 - 121 and for technical data, see page 124 - 126. 3/ Adjustment of air volume • Infinitely variable control of all required air volumes Safety 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 acc

Test certificate Pressure drop and noise level The Strulik damper allows an infinitely variable control of any required air volume. The adjustment is made according to the accompanying diagram. The valve core is locked with a counter nut in the chosen Volume flow rate m3/h
