  • 1220 Fire Smoke Damper
    1220 Fire Smoke Damper

Model Series 1220 and 1220-3 Combination Fire/Smoke Dampers provide the ultimate in fire containment and smoke control for both static and dynamic smoke management systems.

They utilize an innovative inter-locking double-skin airfoil blade design that provides a flame and smoke seal, eliminating the need for synthetic blade seals which burn out during fire conditions, and maintains its leakage class up to 2000°F (1093°C) - a feature no other fire/smoke damper in the industry can offer! Ideal for use where building codes require both a fire damper to protect ductwork penetrations in fire separations and a leakage rated damper for use in smoke management systems, it is available with Leakage Class I or II at 250°F (121°C) or 350°F (177°C). Available at standard dynamic velocity/pressure rating of 2000 fpm @ 4" w.g. (10 m/s @ 1 kPa), UL tested with extended ratings up to 4000 fpm (20 m/s) and 8" w.g. (2 kPa). Model Series 1220 and 1220-3 have been specially designed and tested to provide premium performance and are AMCA licensed. Qualified for installation with airflow in either direction and inverted mounting.
