1 Ordering example: Damper BKUNK90 Test certificate Z Resistance class K90/K30 in BKUNK90/EE/B=797xH=400xL=400 Standard damper length; on request, special dimensions are available Dimensions B x H (width x height) in mm, side H = operating side Accessories: e.g. electrical limit switch, see page 47 Fire damper of fireproofing plates Please note: State any requests separately, e.g. onesided (operating side BS or wall side MS), twosided or completely without duct connecting profile. Please note: A special documentation has not been prepared for the BKUNK90, as the fitting positions are the same as for our damper. There is a difference in dimensions: The BKUNK90 housing and damper blade is 40 mm (: housing = 50 mm, damper blade = 60 mm). In addition, the BKUNK90 is always supplied with an electric motor according to page Tender text: page 22. Technical data and fitting positions: page Dimensioning of suspensions according to weight table no. 4 and 5: page Blade projections: page 44. Design diagrams: page Corrosion test The BKUN has achieved a positive test result during tests with sulfur dioxide SO 2 (high content of damaging gases) according to IEC 68 Part 242 and salt spray, cyclic (sodium chloride solution) according to IEC 68 Part ) See page for technical data, dimensions and installation examples of our damper. The thickness of the housing wall differs (BKUN = 40 mm) and also the damper blade (BKU = 60 mm, BKUN = 40 mm). 21

Installation provisions The dampers may also be mounted with a vertical axis of rotation of the damper blade into walls of concrete, brickwork according to DIN 1053, wall panels of concrete, gas concrete, gypsum according to DIN and at least 40 mm thick partition walls; this also applies to corresponding shaft walls and the walls of vertical ventilation ducts. The distance between the housing walls of the dampers is ca. 100 mm. Expansion compensation Combustible flexible spigots of at least standardflammable materials (class B2 according to DIN 4102), min. 10 cm long (when installed), shall be arranged between the damper and the ventilation duct in case of the following applications: within walls according to Din 1053, which are less than 100 mm thick, within light partition walls, within shaft walls, within gypsum wall panels. Force transmission within walls The dampers within walls, outside of walls and directly in front of walls shall only be connected to such ventilation ducts that due to their design or fitting position cannot apply considerable forces to the dampers or walls in case of fire. 25
