RDFU PREMIUM RADIATION DAMPER FOR ULTRA GREEN
™
AND ULTRA PRO
™
FANS.
When the air temperature passing through the damper exceeds 165°F the
fusible link melts, triggering the thermal fabric to automatically close across
the damper. Airflow is interrupted by a flame and heat barrier, preventing
the rapid spread of fire to other areas.
