S-SA1 Rectangular Smoke Control Dampers

S-SA1 smoke control dampers are designed to operate with mechanical or natural smoke and heat extraction systems. They provide effective removal of poisonous gases, smoke, and fire and can also supply clean air to fire compartments. They are actuator-operated without a spring. S-SA1 has both an open and closed safety position. Power is necessary to operate the smoke control dampers. 

S-SA1 dampers have been designed for duct installations that end with a grille. They are not suitable for installation on a wall or a ceiling. The casing of the S-SA1 is made of galvanised sheet metal. The blades are made from calcium silicate boards with a silicone rubber gasket to prevent any possible leaks of smoke or heat.
