DIGITAL OR ANALOG CONTROLS • PRESSURE
INDEPENDENT • CONSTANT OR VARIABLE VOLUME
MODELS: D3001 AND A3001 WITH BOTTOM MOUNT
CONTROLS LOCATION (OPTION OB)
Standard Features:
• Bottom mount controls location with
vertical drive shaft (option code OB).
• 22 ga. (0.86) zinc coated steel casing,
mechanically sealed, low leakage
construction. Leakage is less than 1% of
nominal flow at 1" w.g. (250 Pa).

16 ga. (1.61) corrosion-resistant
steel inclined single blade damper with
extruded PVC seals (single blade on size
4, 5, 6). 45° 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.
