Combination Fire and Smoke Damper FSD36 - Class II V-Groove Blade

The FSD36 Combination Fire/Smoke Damper is both UL555 and UL555S Classified, and rated as a 1-1/2 hour fire damper and a Leakage Class II 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
