Nailor - Curtain Fire Dampers

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.

Extruded Aluminum • Airfoil Blade Premium Performance
• Model Series 1280 Nailor’s premium choice for applications where a leakage rated damper is required as part of a static smoke control or dynamic smoke management system. Features include as smoothly contoured extruded aluminum airfoil blade and compression type seals that have been specially designed to offer not only the lowest leakage class available with airflow in either direction, but also ultra-low pressure drop characteristics. Together with maintenance-free concealed linkage out of the airstream, the design minimizes unwanted turbulence and noise generation.

Steel Airfoil Blade • Premium Performance
• Model Series 1210 dampers feature an innovative inter-locking double-skin airfoil blade design that eliminates the need for combustible blade seals to maintain leakage class.The unique blade design combines high performance and low pressure drop while providing complete flame and smoke seal under fire conditions. Designed and tested to offer the lowest leakage class available with airflow in either direction, the 1210 Series is perfect for applications where a leakage rated (smoke) damper is required as part of a static smoke control or dynamic smoke management system.

Vee-Style Blade
• Model Series 1260 dampers are a ruggedly built yet economical choice for use where a smoke barrier has been penetrated by ductwork or where a leakage rated damper is required in a static or dynamic smoke control system. The1260 Series dampers are classified to UL Standard 555SClass I, II, or III at 250°F or 350°F Elevated Temperatures,and are available with type B and C enclosures for small sizes and round ductwork. Featuring a vee style blade design for strength.

True Round Smoke Damper
• Model 1290 - Nailor’s true round smoke damper, Model 1290S is ideal for applications where building codes require a leakage rated smoke damper for operational smoke control in static or dynamic smoke management systems. The 1290S damper is an economical true round smoke damper designed and qualified for round ductwork. Features include a sturdy beaded casing for superior rigidity and a laminated blade that is double bolted to axles for positive connection. The1290S smoke damper offers the lowest leakage class available and is qualified for installation with airflow in either direction.
