AIRFOIL
Nailor's D1200 Series multi-blade fire damper provides the ultimate in fire containment for both static and dynamic HVAC systems. The D1200
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 D1200 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 D1200 has a 1 1/2 hour UL label suitable for
use in separations with fire resistance ratings of less than 3 hours. Model Series D1200-3 has a 3 hour UL label suitable for use in separations
with a fire resistance rating of 3 hours or more. Features include a unique airfoil blade design and maintenance-free concealed blade linkage
for extremely low pressure drop and minimal turbulence and noise. Rugged hat-channel frame is reinforced with die-formed corner gussets
for superior rigidity. Industry proven high torque spring/fusible link with over-center knee lock design provides the security of assured closure
under fire condition. Supplied as standard with an internal hand locking quadrant to hold blades in open position or balance the system, the
D1200 Series is available with factory fitted sleeve ready for installation and choice of transition styles to suit duct size and type. Premium
performance, versatility and assured closure make the D1200 Series an excellent choice for the majority of today's applications.
