Application
– For information on how to limit such loads
please refer to the guideline regarding fire
protection requirements on ventilation systems
(Lüftungsanlagen-Richtlinie, LüAR)
– As ducts may expand and walls may become
deformed in the event of a fire, we recommend
using flexible connectors for the following
applications: installation in lightweight partition
walls, in lightweight shaft walls,
with fire batts, and in lightweight fire walls
– Flexible connectors should be installed
in such a way that both ends can compensate
both tension and compression
– Flexible ducts can be used as an alternative
– For certain heights an extension piece
may be required, see table
– The fixing holes in the flexible connectors
and extension pieces match those
in the fire damper flanges
– Flexible connectors
are also available separately
Materials and surfaces
– Flexible connectors made of galvanised steel
and fibre-reinforced plastic
– Fire resistance properties to 4102; B2
K 4 – 1.1 – 29
