Construction features
– Rectangular or square construction,
rigid casing, both flanges with fixing holes
– Suitable for the connection of ducts,
spigots, flexible connectors or a cover grille
– The release mechanism is accessible
and can be tested from the outside
– Two inspection access panels
– Remote control with spring return actuator
Materials and surfaces
Casing:
– Galvanised sheet steel
– Galvanised sheet steel,
powder-coated RAL 7001
– Stainless steel 1.4301
Damper blade:
– Special insulation material
– Special insulation material with coating
Other components:
– Damper blade shafts
and driving linkage made of stainless steel
– Brass or stainless steel bearings
– Seals of polyurethane or elastomer
The construction variants with stainless steel
or powder-coated casing meet even more critical
requirements for corrosion protection.
Detailed listing on request.
Installation and commissioning
Installion is to be carried out according
to the operating and installation manual
Mortar-based installation:
– In solid walls and ceiling slabs
– In non-load-bearing solid walls
with flexible ceiling joint: with installation kit GM
– In lightweight partition walls and fire walls
with metal support structure
and cladding on both sides
Dry mortarless installation:
– In solid walls: with installation kit
and installation subframe E1/E2
– In lightweight partition walls and fire walls
with metal support structure and cladding
on both sides: with installation kit ES
– In lightweight partition walls
with metal support structure,
cladding on both sides and flexible ceiling joint:
with installation kit GL100
– In shaft walls with or without
metal support structure
and cladding on one side:
with installation kit ES
– On the face of solid walls:
with installation kit WA or WA short
– Adjacent to solid walls: with installation kit WV
– Remote from solid walls: with installation kit WE
– Remote from solid ceiling slabs:
with installation kit WE (in horizontal duct)

Maintenance
– The functional reliability of the fire damper
must be tested at least every six months;
this has to be arranged by the owner
of the ventilation system; functional tests
must be carried out in compliance
with the basic maintenance principles stated
in EN 13306 and DIN 31051. If two consecutive
tests, one 6 months after the other,
are successful, the next test can be
conducted one year later.
– A functional test involves closing the damper
blade and opening it again; with a spring return
actuator this can be done via remote control
– Fire dampers must be included in the regular
cleaning schedule of the ventilation system.
– For details on maintenance and inspection,
refer to the installation and operating manual
