Construction

Peerless' Industrial Blower A series solves your most demanding industrial air handling applications with heavy-gauge housings, direct or belt drives, lip and flange connections, and meticulously welded steel frames.

Wheel
Our high-efficiency "Peerless" wheel design features precision-fabricated impeller blades that are fully welded to a spun wheel cone, balanced against a CNC laser-cut backplate and cast-iron hub.

  • Flat Blade Backward Inclined Wheel.
  • Dynamic Factory Balanced.
  • Clockwise or Counter-clockwise Rotation.
  • 15,000 FPM Wheel Tip Max Speed.

Frame
Indoor/outdoor, open-member steel frames with pedestal motor mounts keep 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 fully rotated to reposition the discharge at any of the pre-drilled intervals, allowing for a wide range of installation and ducting configurations. Housing rotation does not require rebalancing.

  • Factory or Field Repositioning.
  • A-9 to A-17 have 22.5° Intervals.
  • A-19 to A-23 have 15° Intervals.
  • A-26 to A-33 have 11.25° Intervals.

Connections
Depending on the Arrangement specified, inlet and discharge ducting flange or ducting lip connections are available. See product literature for each model's standard connections.

  • Ducting Flange and Lip Connection.
  • Check Literature for Standard Connections by Model.

Finish
Standard paint finish is a baked polyester coating over phosphatize-cleaned steel materials.

  • Highly Durable Polyester Coating.
  • Steel is Cleaned and Prepped Prior to Coating.
  • High Abrasion Resistance for Long.

Drive System
Configure as either an adjustable pitch V-belt or direct drive, with heavy-duty motor base rails, ground and polished keyed shafts, and self-aligning normal duty bearings.

  • V-Belt or Direct Drive.
  • Factory-Set RPM Available.
  • Single Speed, TEFC, Inverter Duty Motor.
  • 100K Run Hour Bearings

Options

Light fume and particulate-carrying airstreams especially call for performance- and resilience-boosting upgrades, and Peerless' Industrial Blower A series meets the call with the below factory options.

Weather Cover
The solid sheet metal Weather Cover installs over the belt drive and motor frame, offering weather protection without the need of a separately constructed penthouse or canopy.

  • Eliminates Separate Canopy Cover.
  • Solid Metal Protection.
  • Removable for Maintenance.

Belt Guard
Our heavy-duty Belt Guard is fabricated from expanded metal and installed over the V-belt drive end of the fan, providing personnel protection from the drive's moving parts.

  • Added Personnel Protection.
  • Covers All Rotating Parts.

Vibration Rails
For sound and vibration sensitive applications, Peerless can provide spring or rubber-in-shear Vibration Isolation Rails and Isolation Pads.

  • Reduces Acoustical Impact.
  • ​Isolates Vibration.

Automatic Outlet Damper
Protecting the fan from backdrafts, rain, and snow, our corrosion-resistant Outlet Damper securely attaches to the fan outlet. Choose from automatic, motorized, or manual operation. Outlet dampers are not available with mesh screens.

  • Protects Against Backdrafts.
  • Holds Weather Out.
  • Corrosion Resistant.

Finishes
To help protect against the abuse of particulates, greases, and acids, Anti-Corrosion Paint and Finish options can avoid premature housing damage in very aggressive applications.

  • Combats Very Aggressive Applications.
