Design
The casing and the blades of the S-BA2 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 S-BA2. They also give access for easy connection.
