Model Series 1220SS and 1220SS-3 Combination Fire/Smoke Dampers are ideal for high humidity, mildly corrosive environment applications where building codes require both a fire damper for the protection of ductwork penetrations in walls and a leakage rated damper for operational smoke control on static or dynamic smoke management systems. Features include an airfoil blade, low pressure drop frame design, and maintenance free concealed blade linkage for superb air performance and minimal turbulence and noise. Optional Type 316 Stainless Steel construction is available for more severe environment applications.
