Wheel
Heavy die cast aluminum, straight radial blade design that self-cleans during use, maintaining its balance and assuring efficient airflow even in particulate-heavy conditions.

• Heavy-Duty Die Cast Aluminum.
• Dynamically Factory Balanced.
• Self-Cleaning Design.
• High Efficiency.

Housing
All fan housings can be fully rotated to reposition the discharge at any of eight pre-drilled 45° intervals, allowing for a wide range of installation and ducting configurations.

• 45° Rotation Intervals.
• Factory or Field Repositioning.
• Housing Rotation Does Not Require Rebalancing.

Rotation
Standard clockwise wheel rotation, bottom horizontal discharge position. Other rotations and discharge orientations can be supplied upon request.

• ​​Clockwise Wheel Rotation Standard.
• Optional Counter-Clockwise Wheel Rotation.

Frame
Indoor/outdoor, open-member steel frames keep motors, drivetrains, and wheels in alignment longer than formed sheet frames, resulting in longer maintenance intervals.

• Fully-Welded Steel Frame.
• Easy Maintenance Access.
• Fewer Alignment Adjustments Needed.

Drive System
Adjustable or fixed V-belt drive with cast iron adjustable pitch sheaves, heavy-duty motor base rails, ground and polished keyed shafts, and motors are fixed-mounted onto a welded base frame.

• Adjustable Motor Base for Belt Tensioning
• Factory-Set RPM Available.
• Single Speed, TEFC, Inverter Duty Motor.
• Explosion Proof Motor Options.
