Fire and Smoke Damper Has Lowest Pressure Drop

摘要

Ruskin's fire/smoke damper model FSD60LP was invented to provide the lowest pressure drop in HVAC ductwork, especially in smaller sizes. Its aerodynamic low-profile blade and integral sleeve frame combine to deliver great performance at a great value. The FSD60LP also features a 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.
