Ceiling Dampers

For over thirty years, Nailor Industries has been committed to the development of life safety products such as the 0700 Series CeilingDampers. This commitment has helped foster industry standards, as well as provide worry free fire protection solutions that benefit today’sbuilding designers, owners and occupants. Approved for use in lieu of hinged door type dampers in ULfloor/ceiling or roof/ceilingassemblies, the Nailor 0700 Series provides a fire and heat barrier that has been tested and qualified to the most exacting standards. Forsquare and rectangular applications, Model 0716 is available with standard blade construction or low profile blades, Model 0716-4. Roundduct applications are covered by Model 0722. Nailor’s new Model 0720 features a spring loaded curtain design that maximizes free areawhile providing a low overall profile. Other Series 0700 particulars such as the Adjustable Fusible Link option, ideal for balancing at thegrille/diffuser, and Models 0755 thru 0762, suitable for use in wood truss ceiling assemblies, have been developed to meet specificrequirements in today’s building systems.

Ceiling Radiation Damper • For Square, Rectangular or Round Duct

Ceiling Radiation Damper for Square, Rectangular or Round Duct
• Models 0716, 0716-4, 0714 and 0722 - Nailor ceiling dampers, or ceiling radiation dampers as theyare commonly called, are designed to function as a fire andheat barrier in air duct openings penetrating fire resistivemembrane ceilings. Models 0716, 0716-4 and 0714 are for use in square or rectangular applications and Model 0722 isfor use in round applications, in lieu of hinged door type dampers in any UL floor/ceiling or roof/ceiling assembly with up to a 3 hour fire resistance rating where air ducts are allowed.


Ceiling Radiation Damper • Adjustable for Square, Rectangular or Round Duct
• Models 0716A, 0716-4A and 0722A - Nailor ceiling dampers with adjustable volume control option are designed to function as a fire and heat barrier in air duct openings penetrating fire resistive membrane ceilings. The adjustable volume control mechanism allows the blades to be adjusted for balancing of airflow through thediffuser. Under fire conditions the fusible link will close the damper, regardless of volume setting. Models 0716A and0716-4A are for use in square or rectangular applications and Models 0722A is for use in round applications, in lieu of hinged door type dampers in any ULfloor/ceiling or roof/ceiling assembly with up to a 3 hr. fire resistance rating where air ducts are allowed.


Ceiling Radiation Damper • For Square or Rectangular Duct
• Model
0720 - The Nailor ceiling radiation damper, which functions as a fire and heat barrier in air duct openings thatpenetrate fire resistive membrane ceilings, is for use in lieuof hinged door type dampers in any ULfloor/ceiling assembly with up to a 3 hour fire resistance rating where airducts are permitted. Model 0720 features a specially designed ‘pull across’ insulated curtain that provides a low overall profile, making it ideal for use in applications where the available duct drop height for installation is limited. The compact curtain design also maximizes free area in the openposition.


Thermal Insulating Blanket
• Model 0725 / 0726
- Nailor Thermal Blankets are designed to insulate the exposed back pan area of a steelceiling diffuser that may be used in ULClassified floor/ceiling or roof/ceiling assemblies with up to a 3 hour rating. The insulation protects the floor/roof structure above from theintense heat that radiates through the diffuser pan during fireconditions. Athermal blanket is used in conjunction with aceiling radiation damper that protects the neck opening ofthe diffuser, to provide complete protection of the opening in the ceiling membrane. Model 0725 thermal blanket is for use with 0722 ceiling damper models in round neck applications. Model 0726 thermal blanket is for use with 0714, 0716 and 0720 ceiling damper models in square neck applications.


Ceiling Radiation Damper • For Wood Truss Ceiling Assemblies
• Models 0755, 0756 and 0757
- Nailor Ceiling Radiation Dampers have been designed and tested for simple installation in specific ULdesign wood truss ceiling assemblies. They are ULClassified for use in 1 hour rated UL floor/ceiling design numbers L550 and L562, and roof/ceiling design numbers P531 and P538. Model 0755 ships complete with thermal blanket and top inlet round ductconnection. Model Series 0756 features a factory sheet metal plenum with side duct connection collars. Model Series 0757 is designed for side duct connection collars and can be supplied with or without the fiberglass ductboard plenum.


Ceiling Radiation Damper / Register Box for Wood Truss Ceiling Assemblies
• Model 0758, 0759, 0760, 0761 and 0762
