FK90K fire dampers, series FK92K, are fitted with maintenance-free thermal-mechanical release mechanisms or
with thermal-electrical release mechanisms on the spring return actuators.
Release
occurs at a nominal temperature
of
70°C
or
95°C
. Coated release elements provide increased corrosion protection.
Electric spring return actuators also close the fire dampers if the supply voltage is interrupted. They reopen the fire
dampers as soon as the voltage is present again.
Release mechanisms and operation units can be replaced on site!
