Construction

Precision continuous welding, computerized bearing selections, and advanced manufacturing techniques assure that your high-volume ventilation needs will be more than covered with Peerless' PowerFoil AF series.

Wheel
Our high-efficiency "Peerless" wheel design features hollow, heavy-gauge airfoil section blades, aerodynamically engineered and fully welded to a spun wheel cone, balanced against a CNC laser-cut backplate and cast-iron hub.

  • One-Piece High Strength Steel Airfoils.
  • Extremely Low Noise Levels.
  • Dynamic Factory Balanced.
  • Optimum Trouble-Free Performance.

Inlet
For low-turbulence inlet airflow and balanced rotation, our inlet cones are stamped or rolled from single sheets, free of seams and welds.

  • Rigid Streamlined Inlet.
  • Single-Piece Construction.

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.

Housing
All fan housings can be factory set at any of eight 45° intervals, allowing for a wide range of installation and ducting configurations. Housings are welded and not field adjustable.

  • 45° Fixed Discharge Intervals.
  • Factory Welded Outlet Position.
  • Fewer Bolted Connections to Maintain.

Drive System
The Airfoil Blower series features a V-Belt drive with cast iron adjustable or fixed pitch sheaves, heavy-duty motor base rails, ground and polished keyed shafts, and self-aligning normal duty bearings.
