through ductwork to adjacent designated
fire compartments
Classification
– Class of performance to EN 13501-3,
up to EI 120 (v

Parts and characteristics
– Release temperature 72 °C or 95 °C
(for use in warm air ventilation systems)
– Single-handed operation
– Explosion-proof constructions for zones 1, 2,
21 and 22 with limit switch
or spring return actuator
Construction features
– Rigid, circular casing with spigot connections
suitable for circular ducts. Spigots with lip seal
on both ends, suitable for commercially
available circular ducts to EN 1506
or EN 13180; alternatively with flanges
on both ends. Flanges, to EN 12220
– The release mechanism is accessible
and can be tested from the outside
– Suitable for the connection of ducts,
flexible connectors or a cover grille
– 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 impregnation
Other components:
– Damper blade shaft in stainless steel
– Plastic bearings
– Seals of elastomer
The construction variants with stainless steel
or powder-coated casing meet even more critical
requirements for corrosion protection.
