The damper bodies are usually supplied in galvanised sheet metal without further surface
treatment, alternatively with a special paint Alesta® AS AS3040-7403627 (RAL 7035-GL LIGHT
GREY) with a max. total thickness coating 120 ± 20μm, or the body can be completely made of
class AISI 304, possibly AISI 316L stainless-steel sheet. The damper leaves are made of
asbestos-free fire-resistant boards made of Promatect-H or Promatect-MST. The control damper
devices are supplied in a class AISI 304 or AISI 316L stainless-steel material without other
surface treatments. The main torsion spring in the mechanics is galvanised.
Thermal fuses are made of 0.5 mm thick brass sheet. The connecting material is galvanised, the
moving parts are made of class AISI 304 or AISI 316 stainless-steel.
All moving parts in the damper are conductively connected to the frame, the damper body.

Furthermore, there is a sign of damper non-explosivity on the damper.
The dampers are delivered as bulk cargo. Any other packing methods must be agreed with the
manufacturer in advance. The potential packages will be considered non-returnable and their
price will not be included in the product price.
The dampers are transported by box freight vehicles; no sharp shocks must occur and the
ambient temperature must not 40°C. For handling during transport, the dampers must
be protected against mechanical damages and weather impact. If the customer wishes it, the
dampers can be transported on pallets. During transport, the damper blade must be in the
"CLOSED" position.
Unless another method of reception is specified in the purchase order, the handover of the
dampers to the forwarder shall be understood as reception.
The dampers must be stored in covered buildings, in an environment without aggressive vapours,
gases and dust. A temperature in a range of -5°C and +40°C and a relative humidity of max. 80%
must be maintained in the buildings.
For handling during storage, the dampers must be protected against mechanical damage.
The scope of delivery includes a complete damper and a certificate of quality and completeness
with a stamp of inspection (the certificate is attached to the invoice).
The warranty for fire dampers provided by the manufacturer becomes completely null and void
after any unprofessional handling by untrained workers (see Article 10.1.), when dismantling
electrical components, i.e. limit switches, actuators and thermoelectric starting devices. The
warranty also becomes null and void if the dampers are used for purposes, equipment and
working conditions other than those permitted by these technical conditions or after mechanical
damage during handling.
If the dampers are damaged by transport, it is necessary to draft a report with the carrier upon
acceptance for the possibility of a later complaint.
