F-B90

Fire dampers represent passive fire protection and are designed to utilize compartmentalization to prevent the spread of toxic gases, smoke and fire. The opening and closure of the damper blade can be activated remotely for actuator versions. In case of fire when the air in the duct exceeds 72 °C or 74 °C, the thermal fuse melts in both actuator and manual versions. The melting of the thermal fuse activates the closure of the damper blade automatically. The damper blade is then mechanically locked in the closed position.

• Short body without blade overhangs

• Can be used as Air-transfer grille with cold smoke tightness

• Duct connection from both sides always available

• Symmetric structure and mechanism accessible from both sides

• Fit installation, filling not visible

• Available with smoke detection

• One sided duct connection ended with Grille

F-B90 fire dampers are CE certified following the Construction Products Regulation according to EN 15650:2010. Dampers are tested according to EN 1366-2:2015 and classified according to EN 13501-3 + A1:2009. The fire damper together with its installation form an inseparable part of the fire resistivity rating. F-B90 fire dampers are designed for the installations listed and described in their Handbook.

• Damper connected to duct on both sides or on one side only, installed within standard supporting construction in accordance with EN 1366-2:2015: EI90 (ve - ho i↔o)S

• Damper with grille on both sides and no duct connection (air transfer damper), installed within standard supporting construction in accordance with EN 1366-2:2015: EI90 (ve - i↔o)S & EI120 (ve - i↔o)

There are different types of F-B90 connection. Thus, there are several types of grilles:

The casing of the F-B90 is made of a galvanized sheet metal. Blades and mechanism access doors are made from calcium silicate boards. A foam seal with an intumescent seal that prevents leaks of heat or smoke. The casing has flanges on two sides with a thread to attach to sheet-metal duct flanges. Two sides of the damper have inserts with a thread to attach the grille. The damper casing and two covers on two sides give protection to the mechanism and the actuator of the F-B90. They also give access for easy connection.
