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 wether 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.
