Design of fire damper for suspended ceilings FKU90

The casing and the damper blade are made of temperature-resistant, abrasion-resistant calcium silicate. FKU90 fire dampers have a side connection spigot, thermally expanding seals and a thermal release device for 70°C. This can be operated manually or by motor.

Depending on the type of air diffuser, air deflectors may be required in FKU90 fire dampers for supply air to ensure even air distribution with minimal sound power level.

FKU90 fire dampers are available in nominal sizes from 325 to 600 mm.

The low weight of the FKU90, series FKU91 simplifies handling.

Option

The FKU90 can be optionally equipped with a thermal release in the false ceiling. This contributes to increased safety.
