Models 1280, 1281, 1282, and 1283
Nailor 1280 Series Aluminum Airfoil Blade Smoke Dampers are the premium choice for applications where building codes require a leakage rated smoke damper as part of a static smoke control or dynamic smoke management system. The 1280 Series features a smoothly contoured extruded aluminum airfoil blade and compression type seals that have been especially designed to offer the lowest leakage class available. Together with out of airstream linkage, the design provides an ultralow pressure drop and minimizes unwanted turbulence and noise generation.
Models 1210, 1211, 1212, and 1213
1210 Series Smoke Dampers feature an innovative inter-locking double skin steel airfoil blade design that eliminates the need for combustible blade seals that typically burn off during fire conditions. The unique blade design combines high performance and low pressure drop while providing complete flame and smoke seal. Available at standard dynamic velocity/pressure ratings of 2000 fpm @ 4" w.g. (10 m/s @ 1 kPa), UL tested for extended ratings up to 4000 fpm @ 8" w.g. (20 m/s @ 2 kPa), Model Series 1210 has been designed and tested to provide premium performance. Features include an economical steel airfoil blade, low pressure drop frame design and maintenance free concealed blade linkage for superb air performance, turbulence and noise.
Model 1210M, 1211M, 1212M, and 1213M
Model Series 1210M Modulating Smoke Dampers are classified for use as a volume control damper in applications where building codes require a leakage rated smoke damper. They are equipped with a modulating actuator.
Models 1210SS, 1211SS, 1212SS, and 1213SS
1210SS Series Stainless Steel Airfoil Blade Smoke Dampers are ideal for high humidity, mildly corrosive or, with optional Type 316 construction, more severe environment applications where building codes require a leakage rated damper for operational smoke control in static or dynamic smoke management systems. 1210SS Series dampers are designed and tested to provide premium performance and offers the lowest leakage class available, qualified for installation with airflow in either direction and inverted mounting. Features include a stainless steel airfoil blade, low pressure drop frame design and maintenance free concealed blade linkage for superb air performance, minimal turbulence and noise.
Models 1210VB, 1211VB, 1212VB, and 1213VB
Model Series 1210VB Vertical Blade Smoke Damper is a high performance smoke damper that provides superior protection and versatility. The vertical blade configuration allows for the actuator to be mounted below the damper and is ideal for applications where bottom access is desired or where there isn’t space for a side mounted actuator
Models 1260, 1261, 1262, and 1263
Nailor 1260 Series Smoke Dampers are a ruggedly built economical choice for use where a smoke barrier has been penetrated by ductwork or where a leakage rated smoke damper is required in a static or dynamic smoke control system. The 1260 Series dampers are classified to UL Standard 555S Class I or II at 250°F (121°C) or 350°F (177°C) Elevated Temperatures, and are available with type B and C enclosures for small sizes and round ductwork. Design features include an economical steel vee groove style blade design that provides unmatched strength and durability, low pressure drop frame design and maintenance free concealed blade linkage for superb air performance, minimal turbulence and noise.
Models 1290S and 1290S-SS
Model 1290S is a True Round Smoke Damper ideal for round ductwork applications where building codes require a leakage rated smoke damper for operational smoke control in static or dynamic smoke management systems. Features include a sturdy beaded casing for superior rigidity and a heavy duty 14 ga. (2.0) equivalent laminated blade that is double bolted to axles for positive connection. The 1290S smoke damper is designed and tested to provide premium performance and offers the lowest leakage class available, qualified for installation with airflow in either direction and inverted mounting.
