FEATURES

• Airfoil blade design for low pressure drop and less noise genera­tion.

• One piece interlocking frame design to reduce racking.

• Positive lock axles, noncorrosive bearings and shake proof link­age for low maintenance operation.

• Blade edge seals mechanically lock into the blade for superior
sealing.

OPTIONS

• Factory-installed, pneumatic and electric actuators.

• Enamel and epoxy finishes.

• SP100 Switch Package to remotely indicate damper blade posi­tion.

• Heavier frame construction with U-channel frame.

• Front, rear or double flange frame with or without bolt holes.

• Face and bypass configurations.

NOTE: Dimensions shown in parenthesis ( ) indicate millimeters.
*Units furnished approximately 1/4"

(6) smaller than given opening

dimensions.

APPLICATION

The CD60 is a low leak, galvanized steel damper designed with air­foil blades for higher velocity and pressure HVAC stystems. It meets
the leakage requirements of the International Energy Conservation
Code by leaking less than 3 cfm/sq. ft. at 1" of static pressure and
is AMCAlicensed as a Class 1A damper.

STANDARD CONSTRUCTION

FRAME

5" x 1" x 16 gage (127 x 25 x 1.6) galvanized steel hat channel
reinforced with corner braces for structural strength equal to 11
gage (3.05) channel frames. Low profile 31/2" x 3/8" x 16 gage (89
x 10 x 1.6) galvanized steel channel top and bottom frame on
dampers under 12" (305) high.

BLADES

Galvanized steel airfoil shaped, double skin construction of 14
gage (2.0) equivalent thickness, 6" (152) wide. Parallel or
opposed action.

SEALS

Ruskiprene blade edge seals and flexible metal compressible
jamb seals.

BEARINGS

Stainless steel sleeve.

LINKAGE

Concealed in frame.

AXLES

1

/2" (13) plated steel hex. Removable control shaft extends 6"

(152) beyond frame.

MAXIMUM SIZE

Single section – 60"w x 72"h (1524 x 1829).
Multiple section assembly – Unlimited size.

MINIMUM SIZE

Single blade – 8"w x 6"h (203 x 152).
Two blades, parallel or opposed action: 8"w x 10"h (203 x 254).

TEMPERATURE LIMITS

-72°F (-60°C) minimum and +275°F (+135°C) maximum.

Width

The CD60 may be used in systems with total pressures exceeding 3.5" by reducing
damper section width as indicated. Example: Maximum design total pressure of 8.5" w.g.
would require CD60 damper with maximum section width of 36" (914).
Pressure limitations shown above allow maximum blade deflection of 1/180 of span on
60" (1524) damper widths. Deflections in other damper widths (less than 48" [1219]) at
higher pressures shown will result in blade deflection substantially less than 1/180 of
span.
