Models Series D0100 and D0100SS
Series D0100 (steel) and D0100SS (stainless steel), Curtain Fire Dampers, designed for use in dynamic "fans on" systems where the HVAC system remains operational in the event of a fire, are UL approved for use where building codes require protection of HVAC ductwork penetrations in walls, partitions or floors that have a fire resistance rating of 2 hours or less. The D0100 Series features stainless steel closure springs for assured damper closure under airflow.
Models D0114-12/14/16, D0124-12/14/16, and D0134-12/14/16
Nailor D0104-1X Series Integral Sleeve Dynamic Curtain Fire Dampers include an integral roll formed 4 1/4" frame and sleeve in a single unit. These dampers are a cost effective solution within a limited size and sleeve length range. Stainless steel closure springs for assured closure under airflow and corrosion resistant steel frame and blades for lasting performance.
Models D0114HY, D0124HY, and D0134HY
Series D01X4HY Hybrid Fire Dampers are designed for larger duct sizes that exceed the size limitations of dynamic curtain fire dampers and are a more economical solution than a multi-blade fire damper. The D01X4HY Hybrid Dynamic Fire Dampers are UL approved for use where local building codes require the protection of HVAC ductwork penetrations in walls and partitions that have a fire resistance rating of up to 2 hours. The D01X4HYs are classified for use in dynamic "fans on" systems where the HVAC system remains operative in the event of a fire and damper closure under airflow is assured. Integral sleeve fire dampers offer convenience and labor savings. The costly requirement to field or shop fabricate custom sleeves is eliminated and dampers ship directly from the manufacturer to the job site – saving time and money. Optional "Quick-Set" retaining angles complete the installation package. Factory fabricated, sized and shipped with damper, they install quickly, provide further labor savings and eliminate the need for any field fabrication.
Models D0110G, D0120G, D0130G, D0114G, D0124G, D0134G
D0100G Series Dynamic Curtain Fire Dampers are designed for use in conjunction with a steel grille when ductwork terminates at an opening in a fire rated wall/partition. This unique product utilizes special grille mounting tabs on the sleeve that eliminates the requirement for unsightly retaining angles which commonly protrude from behind the grille. A steel grille installs over and completely conceals the mounting tabs for a clean, aesthetic finish. The fire damper is offset in the sleeve to accommodate a single or double deflection supply air grille, single deflection supply air register or a return air grille or register. Countersunk screw holes in the grille frame will match to mounting tabs when a Nailor grille is ordered in conjunction with the damper assembly.
Models D0110DOW, D0110GOW and D0120GOW
Model D0110DOW, D0110GOW, D0120GOW are "out of wall or floor" integral sleeve dynamic curtain type fire dampers. Model D0110GOW and D0120GOW are designed for supply or return ducts that terminate at a grille or register. Model D0110DOW is designed for through penetrations (ductwork connected to both sides) where the damper cannot be installed within the plane of the wall. UL approved for use where local building codes require the protection of HVAC ductwork penetrations in walls, partitions or floors that have a fire resistance rating of up to 2 hours. These dampers are particularly suited for use in common steel stud drywall partition designs as narrow as 3 1/2" (89), where a traditional "within the plane of the wall" fire damper installation is not possible.
Model Series 0100 and 0100SS
0100 (steel) and 0100SS (stainless steel) Series Static Curtain Fire Dampers, for use in static "fans off" systems where the HVAC system shuts down in the event of a fire, are UL approved to provide protection of HVAC ductwork penetrations in walls, partitions or floors that have a fire resistance rating of 2 hours or less.
Model 0114-12/14/16, 0124-12/14/16, and 0134-12/14/16

Models 0210, 0220, 0230, and 0240
Series 0200V/H Thinline Frame Static Curtain Fire Dampers are UL approved for use where building codes require the protection of HVAC ductwork penetrations in walls, partitions or floors that have a fire resistance rating of 2 hours or less, classified for use only in static "fans off" systems where the HVAC system is automatically shut down in the event of a fire alarm. Series 0200 Thinline Frame Dampers are only 2" (51) deep making them ideal for installation in narrow fire rated partitions, transfer duct openings, behind grilles or in any other application where space is limited.
Model 0310
Model 0310V/H Wide Frame Static Curtain Fire Damper is UL approved for use where local building codes require the protection of HVAC ductwork penetrations in walls, partitions or floors that have a fire rating of 2 hours or less, classified for use only in static "fans off" systems where the HVAC system is automatically shut down in the event of a fire alarm. The wide frame allows for fewer blades and is ideal for use when maximum free area is desired in situations where space or design does not yield room for a Type B damper style.
Model Series 0100G, 01X4G, 0200G
0100G, 01X4G and 0200G Series Integral Sleeve Static Curtain Fire Dampers are designed for use in conjunction with a steel grille when ductwork terminates at an opening in a fire rated separation. This unique product utilizes special grille mounting tabs on the sleeve that eliminate the requirement for unsightly retaining angles which commonly protrude from behind the grille. The steel grille installs over and completely conceals the mounting tabs for a clean, aesthetic finish. 1 1/2 hour rated for use in 2 hour fire separations or less, classified for use in static "fans off" systems where the HVAC system shuts down in the event of a fire alarm.
