Combination Fire/Smoke Dampers

As today’s modern commercial and industrial building construction becomes increasingly life safety oriented, fire containment and active smoke management systems are being utilized to a higher degree as more sophisticated technology is developed and implemented into building codes. The development process begins with the understanding of fire and smoke behavior through the research and study of real life emergency situations, and culminates in the design, testing of, and ultimate use of new products to better control and manage the ravages of fire and smoke. Thus, resulting property damage is minimized and occupant safety is maximized. Nailor Industries commitment to the development of new and existing fire and smoke control technology has resulted in a comprehensive line of premium quality smoke, fire and combination fire/smoke dampers and accessories, available at a reasonable cost and in a timely fashion.

Combination Fire/Smoke Damper Airfoil Blade • Premium Performance
• Model Series 1220 and 1220-3
Model Series 1220 provides the ultimate in fire containment and smoke management for both static and dynamic HVAC systems. It utilizes an innovative inter-locking double-skin airfoil blade design that eliminates the need for blade seals which burn out during fire conditions. Ideal for use where building codes require both a fire damper to protect ductwork penetrations in fire separations and a leakage rated damper for use in smoke management systems, it is available with Leakage Class I or II at 250°F or 350°F. Features include airfoil blade design and maintenance free concealed blade linkage for extremely low pressure drop and minimal turbulence and noise.

Combination Fire/Smoke Damper Airfoil Blade • Out of Wall Mounting
 • Model 1221-OW is an "out of wall"high performance combination fire/smoke damper specifically designed for supply or return ducts that terminate at a grille. The design allows for through the grille access to the damper, actuator and other components. It is perfect for applications where building codes require both a fire damper for the protection of duct penetrations in walls or floors that have a fire resistance rating of 2 hours or less and also require a leakage rated damper for operational smoke control in static or dynamic smoke management systems. It features Nailor’s unique inter-locking double skin airfoil blade design that eliminates combustible seals and provides flame and smoke seal under fire condition sat temperatures up to 2000°F!


Combination Fire/Smoke Damper Airfoil Blade • For Grille Mounting
• Model 1221G is a high performance combination fire/smoke damper specifically designed for supply or return ducts that terminate at a grille. The special factory sleeve with unique 3/4” (19) grille mounting flanges simplifies installation, saves on field labor and eliminates the requirements for unsightly front retaining angles which commonly protrude from behind the grill. Steel grille with correctly located countersunk screw holes is available from Nailor and installs over and c completely hides the mounting flanges. The damper is offset in the sleeve to accommodate a single or double deflection supply air grille, single deflection supply air register or are turn air grille or register.


Combination Fire/Smoke Damper
• Model Series 1270 combination fire/smoke damper, with sturdy triple-vee style blades and a rugged mitered corner hat channel frame design that virtually eliminates racking, provides 1 1/2 hour UL labeled fire protection suitable for use where ductwork penetrates a wall or floor with a fire resistance rating of 2 hours or less. The 1270 Series is also UL tested and labeled for use as a Class I through III Leakage Rated Damper for smoke control applications in both static or dynamic HVAC system designs. Available with factory fitted sleeve (Model 1271), and a variety of actuators and options to suit each application, the 1270 series is a versatile and economical performer suitable for most commercial applications.


Tunnel Corridor Combination Fire/Smoke Damper • Airfoil Blade
• Models 1221C-1 and 1221C-2 Airfoil Blade Tunnel Corridor Combination Fire/Smoke Dampers are for use where ductwork penetrates the ceiling of an interior corridor of a building, creating a horizontal opening that requires protection. Model 1221C-1 is suitable for use with a steel grille or diffuser when the duct terminates at the ceiling. Model 1221C-2 is suitable for use when the duct is required to continue down past the ceiling level. Each unit is supplied factory mounted in a suitable sleeve complete with upper retaining angles.


Tunnel Corridor Combination Fire/Smoke Damper
• Models 1271C-1 and 1271C-2 Tunnel Corridor Combination Fire/Smoke Dampers are for use where ductwork penetrates the ceiling of an interior corridor of a building, creating a horizontal opening that requires protection. Model 1271C-1 is suitable for use with a steel grille or diffuser when the duct terminate sat the ceiling. Model 1271C-2 is suitable for use when the duct is required to continue down past the ceiling level. Each unit is supplied factory mounted in a suitable sleeve complete with upper retaining angles.

Combination Fire/Smoke Damper
• Model 1290FS - Nailor’s true round combination fire and smoke damper, is ideal for applications where building codes require both a fire damper to protect air system penetrations in walls or floors that have a fire resistance rating of up to 2 hours and also require a leakage rated damper for operational smoke control in static or dynamic smoke management systems. It is an economical true round combination fire/smoke damper designed and qualified for round ductwork passing through metal drywall partitions or masonry walls. Features of the damper include a sturdy beaded casing for superior rigidity and factory supplied retaining plates for fast, secure installation. The 1290FS offers the lowest leakage class available and is approved for vertical or horizontal installation.
