FR90 re dampers
Description
All-round single-piece galvanized sheet steel casing.
Casing tightness class C according to EN 1751.
Moulded push-t connections with lip seals for spiral
duct according to DIN 24145, for exible pipe and for
similar ducts of ventilation and air conditioning systems.
All-round press-moulded beading over the whole length
of casing ensures necessary strength and free move-
ment of the damper blade even with large dimensions.
Low pressure drop and a very low noise level are thus
achieved.
Replaceable damper blade made of high-tempera-
ture-resistant, abrasion-proof calcium silicate with
wear-resistant elastomer seals. Damper blade leak tight-
ness class 3 according to EN 1751.
Option: Casing with powder coating. ⇒ see page 6
Option: Damper blade with metal cover (not replaceable)
made of galvanized steel or 1.4301 stainless steel.
Enclosed, maintenance-free drive mechanism in the
area of the casing wall as a self-locking transmission
for break-proof torque transmission. Sealed drive axles
made of stainless steel, with red metal bearings. Ther-
mal release mechanisms for 70°C or 95°C nominal tem-
perature. The operation units can be actuated manually
or electrically. ⇒ see pages 4 and 5
Release mechanisms, operation units and electric actu-
ators are enclosed and with a spring return. They are
maintenance-free, can be connected in a form-locking
or force-tting manner, are easy to replace and can be
easily retrotted as required.
For installation with horizontal or vertical damper blade
axles and in intermediate positions. Air ows are pos-
sible from each connection side.
Connection to ventilation ducts made from non-combus-
tible or combustible materials is possible, also protective
grille.
Installation spacings from 15 mm possible.

Options:
FR90 re dampers in these sizes achieve re resistance periods of up to 120 minutes if they are installed in accordance with
the following stipulations. Installation types in, on or remote from rigid walls and ceilings or metal stud walls, in wooden walls and
ceilings and in ceilings with steel frames with a minimum thickness and re resistance period. If the walls, ceilings have a re
resistance period of less than 120, 90 or 60 minutes, the re resistance period of the FR90 re dampers is reduced accordingly;
partly if the minimum thickness is lower.

FR90 re dampers, series FR92, are tted with maintenance-free thermal-mechanical release mechanisms or with
thermal-electrical release mechanisms on the spring return actuators. Release occurs at a nominal temperature of
70°C or 95°C. Coated release elements provide increased corrosion protection.
Electric spring return actuators also close the re dampers if the supply voltage is interrupted. They reopen the re
dampers as soon as the voltage is present again.
Release mechanisms and operation units can be replaced on site!
