From now on, maintenance-free FR90 fire dampers of the FR92 series can also be installed in a ventilation duct lined on 2 or 3 sides with L90. With this option - already known for FK90 and FK90K fire dampers of the 92 series - Wildeboer now offers even more flexibility for planning and installation. This means that different solutions can be used in the same installation situation - with greater planning reliability and less time required.
When installed directly under the ceiling or in the transition from wall to ceiling, the low installation height allows considerable space savings. An L90-clad ventilation duct can pass through both a solid wall and a metal stud wall. The ceiling or wall adjacent to the cladding must be of solid construction. Two corresponding connection frames are required for installation. The FR90 corner brackets are also included in the scope of delivery. In this way the installation of FR90 fire dampers on site is quick and professional.
Mounting frames simplify installation and acceptance, shorten the installation time and thus save time and costs. Experts recognise the professional installation of the product even after completion of the work. Interfaces between the trades are clearly defined and simplify coordination on site. The time-consuming proof or elaborate documentation of the correct installation of the fire damper is no longer required.
The Wildeboer installation frames can be ordered separately or pre-assembled ex works together with the FR90 fire damper. Mounting frames and fire dampers are usually delivered within 72 hours - this also ensures progress on the construction site.
