Construction

Reinforced structural frames, all-weather resistant finishes, and fully balanced wheels are just a few of the many features included in Peerless' Plenum Fan PL series.

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

  • Flat Blade on Models PL150 to PL245.
  • Airfoil on Models PL270 to PL490.
  • Dynamic Factory Balanced.
  • Clockwise or Counter-clockwise Rotation.

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.

Open Design
Open plenum fans are designed for installation into existing field-erected or factory-built air handling units, pressurizing the air plenum in which the fan operates directly.

  • Space-Saving Design.
  • Eliminates Ducting Transitions into Fan Housing.
  • Flexible Duct Routing In Any Direction.

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.
  • Multiple Motor Options.
  • 100K Run Hour Bearings.
Arrangements

Peerless' Plenum Fan PL series is available in Arrangement 3 and 4 SWSI.

Arrangement 3 SWSI
AMCA Arrangement 3 SWSI utilizes one bearing on either side of the fan impeller (two bearings total), for use with belt driven units. Motor positions W, X, Y, and Z are available. Motor supports can be provided in the field or at the factory.

  • V-Belt Drive with Fully Supported Impeller.
  • SWSI Type: Single Width Single Inlet.
  • Normal Duty, 100k Run Hour Bearings.
  • Remote Mounted Motor.

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.

  • Direct Drive with Overhung Impeller.
  • SWSI Type: Single Width Single Inlet.
  • No Bearings on Fan.
  • Onboard Motor.
Options

Unhoused fan applications are often highly technical to begin with, and Peerless' Plenum Fan PL series offers multiple accessory options to help achieve all of your rigorous requirements.

Radial Inlet Vane
Radial Inlet Vanes smooth airflow turbulence, reduce noise, and improve fan performance. External duct vanes are provided on PL150 to PL245, and nested vanes on PL270 and above.

  • Improve Aerodynamics.
  • Reduce Noise.
  • Automatic or Manual Control.
  • Locking Operator on Manual Vanes.

Safety Enclosure
For additional personnel and fan protection, an optional safety screen enclosure can be provided around the entirety of the impeller.

  • Personnel and Fan Protection.
  • Heavy Gauge Steel Wire Mesh.
  • Securely Framed and Bolted.

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 Drive Parts.
  • Heavy Expanded Metal Mesh.

Vertical Mount
For applications where a vertical fan orientation is preferred, this option reconfigures the drive, motor support, impeller bearings, and shaft connection for optimal performance. 

  • Available in SWSI Only.
  • Balanced Vertical Operation.

Motors
Peerless can provide nearly any special motor specification, including multi-speed windings, stainless steel casings, washdown and other environmental ratings, inverter duty, explosion proof, IEC and other frame sizes, and more.

  • Any Compatible Motor Can Be Provided.
  • Domestic or International Frames.
  • Special Environment Ratings.
