Designed and built for dusty, gritty, and particulate-carrying airstreams at low pressures, Peerless' Radial Blower KE series easily handles your most challenging dirty air demands.

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

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.

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.

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
Direct drive, open ball bearing motors are fixed-mounted onto a welded base frame. No belt tensioning or bearing adjustments are necessary.

  • Factory-Set RPM Available.
  • Multiple Motor Options.
  • Explosion Proof Motor Options.

Peerless' Radial Blower KE series is available in Arrangement 4 SWSI.

Arrangement 4 SWSI
AMCA Arrangement 4 SWSI utilizes a direct-drive motor mounted onto a base frame, attached to the fan housing. The fan impeller is overhung on the motor shaft and does not need separate bearings.

  • SWSI Type: Single Width Single Inlet.
  • No Bearings on Fan.
  • Onboard Motor.

With extreme applications in mind, the Peerless' Radial Blower KE series offers multiple options to extend the fan's service life even in aggressive particulate and soil conditions.

  • Holds Weather Out.
  • Corrosion Resistant.
