Construction

Peerless' Synergy PLENUMclassic series features a unique radial diffuser wheel offering up to 83% total efficiency, ultra-low sound levels, lower horsepower motors, and very high durability.

Radial Diffuser

With larger diameter front- and backplates creating a unique diffusing area to smooth out discharge airflow, our proprietary diffuser wheels convert kinetic energy into pressure energy at very high efficiencies and very low noise levels.

Backward Curved Flat Radial Blades.
Dynamic Factory Balanced.
Counter-Clockwise Rotation.
Steel Wheel.

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.
Galvanized Steel.
Pressure Tap.

Frame

Indoor/outdoor, welded 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

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

Factory-Set RPM Available.
Single Speed, TEFC, Inverter Duty Motor.
Explosion Proof Motor Options.
