Specification Sheet
CENTRIFUGAL ROOF & WALL EXHAUSTERS
Power ratings (BHP) do not include transmission losses.
Performance certified is for installation type A-free inlet, free outlet. Performance ratings include the effects of birdscreen in the airstream.
The sound ratings shown are loudness values in fan sones @ 5’ (1.5m) in a hemispherical free field calculated per AMCA Standard 301.
Values shown are for installation Type A-Free inlet fan sone levels.
*Tri-voltage (115-208-230) is standard on 3/4 through 1 1/2 Hp Single phase motors. Tri-voltage is available for the 1/2 Hp motors. Inquire for price and delivery.
575/3/60 ODP Motors are available for most motor HP’s - Refer to Price List.

•Round duct connection provided at wheel inlet.
Centrifugal Wheel
•Nonoverloading backward inclined for safe operation in ducted systems.

•Plug disconnect switch standard with single speed drip-proof motors.
CONSTRUCTION
ACCESSORIES
Solid State Speed Control:
Control is matched to the motor and blower wheel to allow
continuous reduction in performance allowing adjustments of
airflow for system balancing. CFM is reduced in direct propor-
tion to motor speed reduction. Speed control is only available
for 115 volt single phase. Exhauster performance can be con-
trolled from the ventilated area.

Models CWD are used to exhaust relatively clean air from a variety of indus-
trial, commercial and institutional buildings such as machinery and equipment
rooms, storage areas, office buildings, restaurants, retail stores, schools and
similar buildings.
The nonoverloading centrifugal wheel with its high static pressure capability,
makes it suitable for either ducted or nonducted applications.
The spun aluminum exterior provides a pleasing appearance, weather proof
construction and resistance to corrosion. The low silhouette design is less
noticeable on the building exterior and the removable dome provides easy
access to the fan interior for service and cleaning.
Direct drive units use smaller diameter wheels, resulting in low sound levels
and quiet operation. They have no belts or fan bearings to maintain or adjust
and consequently require very little maintenance.
