APPLICATION

Models CWD are used to exhaust relatively clean air from a variety of industrial, commercial and institutional buildings such as machinery and equipment rooms, storage areas, office buildings, restaurants, retail stores, schools and similar buildings. The non overloading centrifugal wheel with its high static pressure capability, makes it suitable for either ducted or non ducted 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.

Housing
• Spun aluminum dome for weather protection and attractive appearance.
• Ventilated motor compartment with motor out of air stream for long trouble free
service.
• Dome easily removes for access to motor compartment.
• Weather-tight construction with aluminum bird screen.
• Round duct connection provided at wheel inlet.
Centrifugal Wheel
• Non overloading backward inclined for safe operation in ducted systems.
• Statically and dynamically balanced for smooth, quiet operation.
Motors
• Speed controllable motors available on most models.
• Single speed open drip-proof are standard.
• Plug disconnect switch standard with single speed drip-proof motors.

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 proportion

to motor speed reduction. Speed control is only available

for 115 volt single phase. Exhauster performance can be controlled

from the ventilated area.

* Comes with a 5 Year Fan Warranty and a 1 Year Motor Warranty.
