Fire Dampers
The Greenheck DifferenceWhat makes Greenheck different from other damper manufacturers?Perhaps it’s having the most UL certified dampers, or the industry-leading testing capabilities. Most Greenheck dampers meet California State Fire Marshal and NY MEA requirements. Aggressive research and development also keeps Greenheck a major player in the damper industry.

Design and Construction FeaturesMulti blade DFD’s
Reinforced corner designTog-L-Loc®, Greenheck’s reinforced corner design, is incorporated into every Greenheck multi-blade fire damper frame. It provides higher structural rigidity than many competitors’ welded frames. The design also ensures that every frame has square corners, helping prevent blades from binding on the frame and making damper operation much smoother due to less friction.
Maximized free area and minimized pressure dropGreenheck’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 (�02, �27, �52, and �78 mm) – to maximize the free area at any given height and minimize pressure drop. The VSB design also allows for consistent operating characteristics regardless of airflow direction. Traditional damper designs utilize only one blade width – usually 6 or 7 inch (�52 or �78 mm) – which reduces manufacturing costs, but compromises the dampers’ performance capabilities by having cutoff or extended blades and performance robbing oversized closure strips.
Low profile frameLow profile top and bottom frames, standard on all dampers �7 in. (432 mm) high or less, optimize free area on smaller dampers and reduce pressure loss.
TransitionsWhen a rectangular multi-blade fire damper is being used in conjunction with round or oval ductwork, they can be supplied in a factory sleeve with round or oval transitions on both ends of the sleeve. Dampers should be ordered to the duct dimensions.
OptionsSecurity Bars - When a specification requires security bars to be installed with the damper, they can be shipped assembled. Installation of security bars into dampers reduces security risks and reinforces the equipment. Security bars maintain the UL classification for all products. The standard product is welded into the sleeve. The minimum size is 8 in. x 6 in. (203 mm x �52 mm), and the maximum size is limited to maximum size of damper.

Integral Sleeve (X-series)X-series dampers in the FD and DFD model lines have the sleeve formed with the fire damper frame as one piece, giving the most economical sleeved fire damper. The frame with integral sleeve is constructed of galvanized steel.
OptionsSecurity Bars - When a specification requires security bars to be installed with the damper, they can be shipped assembled. Installation of security bars into dampers reduces security risks and reinforces the equipment. Security bars maintain the UL classification for all products.

Steel Stud Connection (SSC) OptionThe Steel Stud Connection (SSC) Option allows fastening of the damper sleeve, up to 36 in x 36 in (9�4 mm x 9�4 mm), directly to the wall's steel stud framing. This option replaces the angles that were previously required for wall installations. See drawing at right.

Helpful installation decalsGreenheck dampers come complete with decals highlighting damper areas that are important to an accurate installation. Our 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 platesRectangular dampers and sleeve assemblies up to a maximum size (W x H, in., W x H, mm) of 80 x 50 (2032 x �270) 50 x 80 (�270 x 2032), or 40 x �00 (�0�6 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. (6�0 mm) require retaining plates on one side only. Damper assemblies exceeding these maximum sizes must be secured with retaining angles or plates on both sides of the partition.
Retaining anglesGreenheck's one piece retaining angle, the POC (literally named for being a “Piece of Cake”) makes Fire Damper installation a breeze. The POC 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 for 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 connectionsGreenheck is the first manufacturer to qualify Ductmate to TDC or Ductmate to TDF connections as a UL approved breakaway connection. The options available are: • Single side attached • Both sides attached • One 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.

Factory Sleeve OptionFire Dampers are available in factory furnished sleeves. Sleeves are galvanized steel and are available in �0 through 20 ga. (3 mm through � mm) thicknesses and lengths up to 48 in. (�2�9 mm).
“K” dimension specifies location of damper within the sleeve. Minimum is 4 in. (�02 mm), maximum is “L” less 4 in. (�02 mm), which allows for 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).
Horizontal dampers must be installed with the “K” dimension on the top. K

Pressure loss through an open damper (change in pressure) is a performance 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 for testing damper pressure drop. Greenheck has tested its dampers for pressure loss in the three test figures shown and provides data for each.
Actual pressure loss found in any HVAC system is a combination of many factors. This pressure loss information, along with an analysis of other system influences, should be used to estimate actual pressure losses for a damper installed in a given HVAC system.
D=Duct lengthW=Damper widthH=Damper height
Pressure LossPressure Loss testing was conducted in accordance with AMCA Standard 500-D. All data has been corrected to represent standard air at a density of 0.075 lb/ft3 (�.2 kg/m3).
Damper Performance Testing Criteria
Greenheck Fan Corp. certifies that the models DFD-2�0, DFD-230, DFDTF-2�0, SEDFD-2�0, and SSDFD-2�0 shown herein are licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 5�� and comply with the requirements of the AMCA Certified Ratings Programs. The AMCA Certified Ratings Seal applies to air performance ratings only.

Codes/Listings/Approvals
Test Standards & CertificationsUL555
This standard governs fire dampers which are intended for use where air ducts penetrate or terminate at openings in walls or partitions, in air transfer openings in partitions, and where air ducts extend through floors as specified in the Standard for 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 or partition to the other. Testing includes cycling, salt spray, dust loading, dynamic closure, fire endurance, and hose stream.
