FSD60 with airfoil multiple blades are recommended in smoke management and smoke control system with pressures up to 1 kPa and velocities 20m/s.
FSD60 meets the following international standard:
• BS476 Part 20 – 4 hours FRP
• UL555 – 1.5 hours FRP
• UL555S – Class I leakage
• Smoke extraction – Continuous operation at 250degC for 1 hour
The FSD60 Combination Fire/Smoke Damper is both UL555 and UL555S Classified. It is rated as a 1-1/2 hour fire damper and a Leakage Class I Smoke damper. It features:
Rated to 3,000 fpm and 4″ w.g.
UL approval for dual directional airflow.
Airfoil blades, which have greater strength, less static pressure drop, superior sealing ability, superior fire protection ability, and produce less noise.
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.
