Construction

Combining self-cleaning radial blade performance and adjustable belt drive flexibility, Peerless' Radial Blower PWB series solves your high-pressure challenges with ease.

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.

Options

High-pressure, low-volume applications can often benefit from functional and performance customization, and that's why Peerless' Radial Blower PWB series offers a wide variety of factory options.
