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 Features
Multi-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 (102, 127, 152, and 178 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
(152 or 178 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 17 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.
OptionsOpen Close Indicator (OCI) - The OCI option provides two switches, one set
of contacts to close when the damper blades are at their open position, and
the other set to close when the damper blades are at their closed position.
The switches are physically linked to a damper blade and therefore give a true
representation of the damper’s position.
Factory Sleeve - Fire Dampers are available in factory 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).

Helpful Installation DecalsGreenheck dampers come complete with decals highlighting damper
areas that are important for an accurate installation. Our decals point out
critical damper areas and include messages like “Do not install screws
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 1270), 50 x 80 (1270 x 2032), or 40 x 100 (1016 x 2540) require retaining angles on one side of the
partition only for 1 1/2 hour dampers. 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 or plates on both sides of the partition.
Retaining AnglesSave time by letting Greenheck install retaining angles for you. You can
order your retaining angles four different ways:
� Single Fastened - one retaining angle �ounted in the location you want
� Single Wrapped - one retaining angle wrapped around the da�per sleeve
and wire tied
� Double Wrapped - the sa�e feature as single wrapped but, with 2 sets of
retaining angles
� Fastened & Wrapped - one retaining angle fastened and one angle
wrapped around the damper
Breakaway ConnectionsGreenheck was the first manufacturer to successfully UL qualify a universal
breakaway duct connection that is co�patible with TDC, TDF, Duct�ate,
Nexus or Ward flange systems. You now have the option to choose the
universal breakaway connection on fire dampers, smoke, and combination
fire smoke dampers. You can order your dampers with breakaway connection
three different ways:
� Universal flange attached to one end of the sleeve
� Universal flange attached to both ends of the sleeve
� One end attached and one shipped loose
S & Drive connection uses drive slip connection on the side of the he��ed
sleeve and S-slip joints are used on top and botto�.
Access DoorsAccording to NFPA 80 (2007 edition) & NFPA 90A (2002 edition), an access door needs to be provided in air
ducts adjacent to each mre da�per, s�oke da�per, or co�bination mre s�oke da�per for �aintenance and
inspection. Save time and money by letting Greenheck install the access door in the sleeve to save on labor
cost in the meld.
Security BarsWhen 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 152 mm), and the maximum size is limited to maximum size of
damper.
Grille TabsThe Grille Tab option provides mounting flanges on the sleeve to ease installation of grilles in the field. The
flanges are concealed when the grille is installed.

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.
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 (1.2 kg/m3).

Codes/Listings/Approvals
Test Standards & Certifications
UL555This 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.
UL555CThis standard governs ceiling dampers which are intended for use in air
handling duct outlets which penetrate membrane ceilings of hourly fire rated
resistive assemblies, or for installation in the ceiling membrane of such
assemblies which utilize the plenum space for return air.
AMCAThe AMCA Certified Rating Program seal assures you that a product line has
been tested to the appropriate AMCA standards in accordance with a legal
license agreement and that the manufacturer's catalogued certified ratings
have been submitted to the AMCA staff for approval prior to publication.
Warnock HerseyThe Warnock Hersey is among the most well-recognized and respected
North American marks of compliance for building codes, association criteria,
and product safety and performance standards. Warnock Hersey, like UL, is
an independent agency which evaluates and tests products to recognized
standards including those dictated by UL, NFPA, and ASTM.
