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 PG122 to PG490.
• Optional Airfoil on Models PG270 to PG490.
• 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 plug fans are designed for installation into existing field-erected or factory-built air handling units or plenum systems, 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
Features a V-Belt drive with cast iron adjustable pitch sheaves, heavy-duty motor base rails, ground and polished keyed shafts, and self-aligning heavy-duty bearings.

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

Peerless' Plug-Pak Fan PG series is available in Arrangement 9 SWSI.

Arrangement 9 SWSI
