Design
The casing and the blades of the F-B90 are made of a galvanized sheet metal. 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.
Composition of materials
Body of the product contains these materials: Galvanized sheet metal; Galvanized steel fasteners; PE tapes and foil
Blades and mechanism access doors of the product contain these materials: Calcium silicate board; Polyurethane foam;
Intumescent strips; Acrylic sealant
The manufacturing processes of these materials agree with local regulations. The product does not contain dangerous
materials.
