Synergy PLENUMclassic
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.
Inlet
For low-turbulence inlet airflow and balanced rotation, our inlet cones are stamped or rolled from single sheets, free of seams and welds.
Frame
Indoor/outdoor, welded steel frames keep motors, drivetrains, and wheels in alignment longer than formed sheet frames, resulting in longer maintenance intervals.
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.
Drive System
Direct drive, TEFC motors are fixed-mounted onto a welded base frame. No belt tensioning or bearing adjustments are necessary.
Synergy PLENUMclassic
Arrangements
Peerless' Synergy PLENUMclassic series is available in Arrangement 4 SWSI.
Arrangement 4 SWSI
AMCA Arrangement 4 SWSI utilizes a direct-drive motor mounted onto a base frame. The fan impeller is overhung on the motor shaft and does not need separate bearings.
