Flexible connector with
flange for FKS-EU-FL
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
for the following applications using flexible
connectors when connecting the fire damper to
rigid ducts: installation into lightweight partition
walls and into lightweight shaft 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 nominal sizes extension pieces
may be required, see table
– The fixing holes in the flexible connectors
and extension pieces match those in the fire
damper flanges (applies only to FKR-EU-FL)
– Flexible connectors are supplied separately
and can are fixed by others
– Flexible connectors
are also available separately
Materials and surfaces
– Flexible connectors made of galvanised steel
(FKR-EU-FL only) and fibre-reinforced plastic
– Fire resistance properties to 4102; B2
– Extension piece made of galvanised sheet
steel (and powder-coated silver grey,
RAL 7001, when used with powder-coated (1)
and stainless steel (2) dampers)
