1)
Temperatures may differ for units with attachments. Details for
other applications are available on request.
2)
Data applies to uniform upstream and downstream conditions
for the fire dampers.
3)
For explosion-proof constructions of the FK-EU see the corre-
sponding operating manual.
4)
Condensation and the intake of humid fresh air have to be avoided as
otherwise operation will be impaired or not possible.
5)
Leakage rate of the fire damper system tested at 300 Pa and 500 Pa
negative pressure.
