These roof exhauster's are used to exhaust air from all types of commercial and institutional buildings such a hospitals and health care facilities, schools, recreational buildings, machinery and equipment rooms, offices, retail stores and similar applications.
The non overloading centrifugal wheel with its high static pressure capability, makes it suitable for either ducted or non ducted applications. It's roof mounting permits location near the area to be ventilated, allowing short duct runs and more efficient operation.
The spun aluminum exterior provides an attractive appearance and is compatible with belt driven Model DB and companion gravity units to make up a complete ventilation system. Direct drive units use smaller diameter wells, 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.
CONSTRUCTION
Housing
- Curb cap has prepunched mounting holes for ease of installation.
- Fan plate isolates motor compartment from contaminated exhaust air.
- Spun aluminum hood and skirt for weather protection and attractive appearance.
- Heavy-gauge motor support for rigidity and strength
- Neoprene isolators for reduction of vibration and sound.
- Quick access to motor compartment for ease of maintenance.
- Conduit passage for easy electrical connection from below roof.
- Aluminum birdscreen and disconnect are included on standard models.
Centrifugal Wheel
- Non overloading for safe operation in ducted systems.
- Backward inclined wheels constructed of noncorrosive aluminum.
- Statically and dynamically balanced for smooth, quiet operation.
Speed Controllable Motors
- Standard motors are single speed, speed controllable and drip-proof.
- All motors are rated for continuous duty.
- Disconnect is standard with single speed drip-proof motors.
- Motors ship mounted as standard.
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.
