Dimensional Data
Standard Features:
• Designed for hospital and other critical
environment applications where IAQ is a
concern.
• 22 ga. (0.86) zinc coated steel casing,
mechanically sealed, low leakage
construction.
• 16 ga. (1.63) corrosion-resistant steel
inclined opposed blade damper with
extruded PVC seals (single blade on size
4, 5, 6). 45
O
rotation, CW to close. Tight
close-off. Damper leakage is less than 2%
of the terminal rated airflow at 3" w.g. (750 Pa).
•1/2" (13) dia. plated steel drive shaft.
An indicator mark on the end of the shaft
shows damper position.
• 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.
• VAV section is lined with 13/16" (21),
thick, 4 lb. density Steri-Liner insulation.
Fiberglass with a reinforced aluminum
FSK facing. Meets the requirements of
NFPA 90A, UL 181 and ASTM C655.
"Notch and tuck" fabrication and full seam
length steel Z-strip construction.
• Right-hand controls location is standard
(shown) when looking in direction of
airflow. Optional left hand controls
mounting is available.
Silencer Section:
• Designed to mate with VAV section for
optimum performance and super quiet
operation.
•
Optimized internal baffle geometry
reduces self-generated noise, minimizes
pressure drop and maximizes acoustic
attenuation.
• 22 ga. (0.86) coated steel perforated
baffles encapsulate fiberglass acoustic
media. Mylar lining with acoustical spacer
isolates material from airstream.
• Internal Steri-Liner insulation on top and
bottom optimizes sound reduction and
eliminates need for external field applied
thermal duct wrap.
Hot Water Coil Section:
• 1/2" (13) Copper tubes and aluminum
ripple fins, 10 per inch.
• 20 ga. (1.00) zinc coated steel casing
Uninsulated.
• Left or right hand connection. Determined
by looking in direction of airflow (RH
illustrated).
• 1/2" (13), 7/8" (22) or 1 3/8" (35) O.D.
male solder sweat connections.
