FSD37 1-1/2 hr V-Groove Blade Combination Fire/Smoke Damper

The FSD37 Combination Fire/Smoke Damper is both UL555 and UL555S Classified, and rated as a 1-1/2 hour fire damper and a Leakage Class I Smoke damper. It features:

Maximum velocity of 2,000 fpm.
Maximum 4" static pressure.
UL tested for dual directional airflow.
Failsafe design, which enables the damper to automatically assume the desired position when fire or smoke (if smoke detector is present) interrupts operational power.
The EFL or PFL heat-actuated release devices permit controlled closure through the actuator and are automatically remote resettable after test, smoke detection, or power failure conditions.
Galvanized steel construction.
