CD60 SUGGESTED SPECIFICATION
DIMENSIONAL INFORMATION
Furnish and install, at locations shown on plans, or in accordance
with schedules, control dampers that meet the following minimum
construction standards. Frame shall be 16 gage (1.6) galvanized
steel structural hat channel with tabbed corners for reinforcement for
11 gage (3.05) structural equivalence. Blades shall be 14 gage (2.0)
equivalent thickness galvanized steel, roll-formed airfoil type for low
pressure drop and low noise generation. Blade edge seals shall be
Ruskiprene type or equivalent suitable for -72°F (-60°C) to +275°F
(+135°C) mechanically locked into the blade edge. Adhesive or clip-
on type seals are unacceptable. Jamb seals shall be flexible metal,
compression type to prevent leakage between blade end and
damper frame. Blade end overlapping frame is unacceptable.
Bearings shall be corrosion resistant, permanently lubricated stain-
less steel sleeve type turning in an extruded hole in the damper
frame. Axles shall be hexagonal positively locked into the damper
blade. Linkage shall be concealed out of airstream, within the
damper frame to reduce pressure drop and noise. Submittal must
include leakage, maximum air flow and maximum pressure ratings
based on AMCA Publication 500. Damper shall meet the leakage
requirements of the International Energy Conservation Code by
leaking less than 3 cfm/sq. ft. at 1" of static pressure and shall be
AMCA licensed as a class 1A damper. Dampers shall be Ruskin
CD60 model.
Specifier Select Options.
SP100: Dampers shall be equipped with factory installed damper
position indication switch package. The switch package shall
include two position indication switches linked directly to the damper
blade to provide full open and full closed damper blade position. The
switch package shall be capable of interfacing with the HVAC con-
trol system and provide remote damper blade position status.
Switch package shall be Ruskin Model SP-100.
Factory Mounted Damper Actuators: If control damper actuators
are required, they shall be furnished and mounted by the damper
manufacturer in their factory. Each damper shall be cycle tested at
the factory prior to shipment.
