These roof exhausters are used for the exhaust of relatively clean air from a wide range of commercial, industrial and institutional buildings such a manufacturing and assembly plants, office buildings, schools, hospitals, restaurants, athletic facilities and many others.

The non overloading centrifugal wheel with its higher static pressure capabilities makes this suitable for either ducted or nonducted applications. It's roof mounting permits location near the area to be ventilated, allowing short duct runs and more efficient operation.

The aluminum exterior provides an attractive appearance. Belt drive results in lower operating RPM and sound levels, making the Model DB well suited to applications where quiet opertion is important. Belt drive also permits easy performance adjustment when needed to balance the total ventilation system.

CONSTRUCTION

Housing

• Heavy-gauge aluminum for extra strength with prepunched mounting hole.
• Neoprene isolators for reduction of vibration and sound.
• Cover easily removed for quick access to motor compartment.
• Water tight conduit tube for easy electrical connection from below roof.
• Aluminum birdscreen and disconnect are included on standard models.
• Stainless steel exterior fasteners.

Centrifugal Wheel

• All aluminum backward inclined wheel.
• Non overloading for safe operation in ducted systems.
• Statically and dynamically balanced for smooth operation.

Drives

• Sized for minimum 150% of drive hosepower.
• Machined cast iron adjustable motor pulleys.
• Adjustable base for belt tensioning.
• Nonstatic oil resistant v-belts.

Motors

• Single speed open drip-proof are standard.
• All motors are rated for continuous duty.
• 182T and larger motors shipped unmounted for field installation.
• Disconnect switch standard with single speed drip-proof motors.

Bearings
