NOTE: UL LISTED POWER ROOF VENTILATOR STANDARD 705 AND 762

* For grease removal applications the fan must be installed per NFPA 96 and with a 40" discharge height and hinged access base.
* Restaurant curbs must be 18" high minimum per NFPA-96.
* Do not use damper for fans in grease removal applications per NFPA 96.

Isolation of the motor and drive components from the air stream and the high velocity vertical air discharge make the model TXB-UL762 ideally suited for the removal of dirty, contaminated and/or high temperature air from processes and buildings. Typical applications include restaurant hoods and similar kitchen exhaust ventilation, fume and smoke removal, laboratory fume hood exhaust and chemical process exhaust.

• Heavy-gauge aluminum housing and prepunched galvanized steel curb cap.
• Enclosed, ventilated motor/drive compartment isolates motor and drives from exhaust air.
• The motor compartment housing easily removes for complete maintenance access.
• Water-tight conduit tube for easy electrical connection without having to wire through the breather tube.
• External weather proof disconnect is included on standard models.

Centrifugal Wheel

• Nonoverloading backward inclined for safe operation in ducted systems.
• Heavy aluminum hub for extra strength.
• Statically and dynamically balanced for smooth operation.

Motors

• Single speed drip-proof motors are provided on standard models.
• All motors are rated for continuous duty.
• Disconnect is standard with single speed drip-proof motors.

Drives

• Sized for minimum 150% of drive horse power
• Machined cast iron adjustable motor pulleys.
• Adjustable base for belt tensioning.
• Static resistant v-belt.

Bearings

• Heavy-duty cast pillow block ball bearing type.
• Prelubricated with zerk fitting.
• Designed for 200,000 hour average life.
