MULTI-BLADE FIRE DAMPERS
GENERAL PRODUCT OVERVIEW
MODEL SERIES 1200
AIRFOIL BLADE FIRE DAMPER
FOR STATIC SYSTEMS
Nailor's 1200 Series multi-blade fire damper is classified for
use only in static "fans off" systems where the HVAC system
is automatically shut down in the event of a fire alarm. The
1200 Series utilizes an innovative inter-locking double skin
airfoil blade design that maintains a complete barrier
throughout the fire test with absolutely no visible through-
gaps. Amazingly, the 1200 Series fire damper gets tighter as
it gets hotter! Ideal for use where building codes require a
fire damper for the protection of ductwork penetrations in
walls or floors, Model Series 1200 has a 1 1/2 hour UL label
suitable for use in separations with fire resistance ratings of
less than 3 hours.

TRUE ROUND FIRE DAMPER
FOR STATIC OR DYNAMIC SYSTEMS
Model 1290F is suitable for use where building codes require
a fire damper for protecting ductwork penetrations in walls or
floors that have a fire resistance rating of up to 2 hours. It is
an economical true round fire damper designed and qualified
for point-of-origin fire containment where round ductwork
passes through metal stud drywall partitions or masonry
walls. Features of the 1290F include the industry proven
over-center/knee lock design with high torque spring/fusible
link closure which provides fail-safe security under fire
conditions. Each damper is supplied as standard with
retaining plates for fast secure installation and a hand
locking quadrant which holds the damper in the fully open
position, but may also be used for system balancing if
required.
