Model 1290F fire damper is ideal for applications where building
codes require a fire damper for the protection of ductwork
penetrations in walls or floors that have a fire resistance rating of
up to 2 hours. The 1290F is classified for use in dynamic "fans
on" systems where the HVAC system remains operative in the
event of a fire. Damper closure under airflow is assured.
The 1290F is an economical true round fire damper designed
and qualified specifically for point-of-origin fire containment
where round ductwork passes through metal or wood stud
drywall partitions and masonry walls or floors.
Features include the industry proven over-center knee lock
design with high torque spring/fusible link closure. The 1290F is
supplied as standard with a crank arm and locking screw which
holds the damper in the fully open position, but may also be used
for system balancing if required.
