Design and Construction Features Multi blade DFD s Reinfced cner design Tog-L-Loc, Greenheck s reinfced cner design, is incpated into every Greenheck multi-blade fire damper frame. It provides higher structural rigidity than many competits welded frames. The design also ensures that every frame has square cners, helping prevent blades from binding on the frame and making damper operation much smoother due to less friction. Maximized free area and minimized pressure drop Greenheck s Variable Symmetrical Blade Design (VSB), available on multi-blade models, uses a combination of four symmetrical blade sizes 4, 5, 6, and 7 inch (102, 127, 152, and 178 mm) to maximize the free area at any given height and minimize pressure drop. The VSB design also allows f consistent operating characteristics regardless of airflow direction. Traditional damper designs utilize only one blade width usually 6 7 inch (152 178 mm) which reduces manufacturing costs, but compromises the dampers perfmance capabilities by having cutoff extended blades and perfmance robbing oversized closure strips.

ptions and Accessies Helpful installation decals Greenheck dampers come complete with decals highlighting damper areas that are imptant to an accurate installation. ur decals point out critical damper areas and include messages like Don t drill holes here. We are the only damper manufacturer to offer these simple yet very helpful tips right on the damper. Single side retaining angles and plates Rectangular dampers and sleeve assemblies up to a maximum size (W x H, in., W x H, mm) of 80 x 50 (2032 x 1270) 50 x 80 (1270 x 2032), 40 x 100 (1016 x 2540) require retaining angles on one side of the partition only. Round dampers and sleeve assemblies up to a maximum diameter of 24 in. (610 mm) require retaining plates on one side only. Damper assemblies exceeding these maximum sizes must be secured with retaining angles plates on both sides of the partition. Retaining angles Greenheck's one piece retaining angle, the PC (literally named f being a Piece of Cake ) makes Fire Damper installation a breeze. The PC simply wraps around the sleeve of the damper, connections are made as described in our installation instructions, and that's it! Simple! Like their rectangular counterparts, round one-piece retaining plates easily wrap around the sleeve of the damper and tighten with the clamping screw f simplified installation. Greenheck has added three new options available on Fire Dampers. The retaining angle options are: Single-fastened provides the angle mechanically fastened to the damper at the location specified Single-wrapped retaining angle is wrapped around the damper sleeve and tied together Double-wrapped is the same as the single-wrapped except with two retaining angles provided Breakaway connections NUT RETAINING PLATE ASSEMBLY CLAMPING SCREW Greenheck is the first manufacturer to qualify Ductmate to TDC Ductmate to TDF connections as a UL approved breakaway connection. The options available are: Single side attached Both sides attached ne side attached and one side shipped loose. S & Drive connection uses drive slip connection on the top and bottom of the hemmed sleeve and S-slip joints are used on top and bottom. Facty Sleeve ption Fire Dampers are available in facty furnished sleeves. Sleeves are galvanized steel and are available in 10 through 20 ga. (3 mm through 1 mm) thicknesses and lengths up to 48 in. (1219 mm). Sleeve K dimension specifies location of damper within the sleeve. Minimum is 4 in. (102 mm), maximum is L less 4 in. (102 mm), which allows f mounting angle installation and duct connection at each end of sleeve. If K dimension is not specified, it will be provided as one half of L dimension (damper centered in sleeve). Hizontal dampers must be installed with the K dimension on the top.

Damper Perfmance Testing Criteria Pressure loss through an open damper (change in pressure) is a perfmance criteria required to appropriately select and apply a fire life safety damper in an HVAC system. Any damper s pressure loss depends on where and how the damper is installed in the HVAC system. AMCA Standard 500-D defines several configurations to be used f testing damper pressure drop. Greenheck has tested its dampers f pressure loss in the three test figures shown and provides data f each. Actual pressure loss found in any HVAC system is a combination of many facts. This pressure loss infmation, along with an analysis of other system influences, should be used to estimate actual pressure losses f a damper installed in a given HVAC system. Fig. 5.3 Fig. 5.2 Fig. 5.5 5D 5D Figure 5.3 illustrates a fully ducted damper. Figure 5.2 illustrates a ducted damper exhausting air into an open area. Figure 5.5 illustrates a plenum mounted damper.

Codes/Listings/Approvals Test Standards & Certifications UL555 This standard governs fire dampers which are intended f use where air ducts penetrate terminate at openings in walls partitions, in air transfer openings in partitions, and where air ducts extend through flos as specified in the Standard f Installation of Air-Conditioning and Ventilating Systems, NFPA 90A. In a fire emergency the fire damper is designed to close and prevent the spread of fire from one side of the wall partition to the other. Testing includes cycling, salt spray, dust loading, dynamic closure, fire endurance, and hose stream. UL555C This standard governs ceiling dampers which are intended f use in air handling duct outlets which penetrate membrane ceilings of hourly fire rated resistive assemblies, f installation in the ceiling membrane of such assemblies which utilize the plenum space f return air.
