Functional description
The fire damper is used as a shut-off device
to prevent fire and smoke from spreading
through ducting in areas with potentially explosive
atmospheres. The fire damper is suitable
for supply air and extract air systems in potentially
explosive atmospheres. For the operation of the
fire damper, the operating and installation manual
and the technical data in the additional operating
manual must be observed.
Use in areas with
potentially explosive atmospheres (ATEX)
According to declaration of conformity
TÜV 11 ATEX 085420 X, the fire damper
may be used in the following areas
with potentially explosive atmospheres.
The ambient temperatures and types of release
and actuation specified in the technical data
must be observed.
RedMax:
– Zone 2: Gases, mists and vapours
– Zone 22: Dusts
ExMax:
– Zones 1, 2: Gases, mists and vapours
– Zones 21, 22: Dusts
