Standard Features:
• Bottom mount controls location with
vertical drive shaft (option code OB).
• 22 ga. (0.86) galvanized steel casing,
mechanically sealed, low leakage
construction. Leakage is less than 1% of
the terminal rated airflow at 1" w.g. (250
Pa).

butterfly damper with a polyurethane
peripheral gasket. 90° rotation, CW to
close. Tight shut-off. Damper leakage is
less the 1% of the terminal rated airflow
at 3” w.g. (750 pa.) and less than 2% at 6"
w.g. (1500 pa.) as tested in accordance
with ANSI / ASHRAE Standard 130.
• 1/2" (13) dia. plated steel drive shaft.
An indicator mark on the end of the shaft
shows damper position.
• Unit sizes 4–16 feature round inlet collars.
• Multi-point averaging Diamond Flow
Sensor. Aluminum construction. Supplied
with balancing tees.
• Rectangular discharge with slip and
drive cleat duct connection.
• Full NEMA 1 type controls enclosure for
factory mounted controls.
• 3/4" (19), dual density insulation,
exposed edges coated to prevent air
erosion. Meets the requirements of
