Series FK120
FK90 fire dampers
Description
Increased corrosion protection through powder coating and stainless steel
Casings coated internally and externally are recommended:
•
metal frames of the damper blades
made of 1.4301 stainless steel
and
– if present – the metal cover as well
•
thermal-mechanical release mechanisms with
corrosion-resistant
(coated)
release element 70°C.
These combinations allow additional corrosion protection for harsh service conditions.
FK90 fire dampers
•
Meet the
hygiene requirements
according to VDI 6022-1, DIN 1946-4 and DIN EN 13779
•
Do not promote the growth of microorganisms
1)
(fungi, bacteria)
.
This reduces the risk of infection for people and also the necessary
cleaning and disinfection work!
•
Are
resistant to disinfectants
2)
•
Are suitable for use in hospitals and similar facilities!
•
Permanently
perform
their
function under high corrosion condi-
tions.
Tested according to EN 15650, annex B with 20% saline solution.
1)
The corresponding
resistance of the materials to fungi and bacteria
was verified by testing the microbial metabolic potential under
DIN EN ISO 846 for all materials in the FR90 fire dampers.
2)
The
resistance to disinfectants
of the materials in the FR90 fire dampers was tested with the disinfectant groups of active ingredients
alcohol
and
quaternary compounds
. These disinfectants are on the list by the Robert Koch Institute, and were used in accordance with the specifications in
the list of disinfectants by the Disinfectants Commission in the German Association for Applied Hygiene (VAH). It has been verified that FR90 fire
dampers can withstand normal use of disinfectants and disinfection methods.
Pressure-joined casing with all-round single-piece design,
made of galvanized sheet steel, leak tightness class C
according to EN 1751. Formed connection flanges, outer
beading and tapered inner beading ensure stability, free

ators are enclosed and fitted with a spring return. They are
maintenance-free, can be connected in a form-locking or
force-fitting manner, are easy to replace and can be easily
retrofitted as required.
For installation with horizontal or vertical damper blade
axles. Air inflow from any connection side. Connection to
ventilation ducts made of non-combustible or combustible
materials, including protective grilles.
Option:
Additional openings on the operation side in the
casing.
