Test certificate Z-41.3-325 Resistance class K90/K60 NW 100/125/160 and 200 Mounting frame for the installation into: ED brickwork or concrete floor EW-L light partition walls, metal support walls EW-L-40 light partition walls, wall thickness 40 mm Test certificate Z-41.3-333 Resistance class K30/0 Essential advantages • • Accessories (optional): MS-E electrical limit switch RT inspection tee SNP-S male sleeve connection NP male-male connector VMT disk valve for overflow opening The BEK-K90 is suitable for the installation into light F90 and F30 partition walls. The damper is mounted directly into the fire protected zone. The effectiveness of the fire protection is guaranteed by the butterfly blades. The dampers may even be mounted subsequently into ventilation systems in order to meet the effective fire prevention requirements. No special fixing arrangements are required (i.e. saving of time and high economy). Essential features 1/ Safety classification. • Official classification: Resistance class K90 and K30 • Release from 72 °C upwards • Maximum sealing between the body and the blades • Flame stability 2/ Low noise level • Insignificant reduction of cross-sectional area • High airflow rate • Any direction of airflow 3/ Sizes available • NW 100/125/160 and 200 Safety The Strulik BEK-K90 and K30 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. 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 and K30 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 accor
