Specifically engineered for the most compact footprint and lowest weight possible, Peerless' Synergy PLUGlight series offers up to 83% system efficiency at extremely low sound levels.
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.
For low-turbulence inlet airflow and balanced rotation, our inlet cones are stamped or rolled from single sheets, free of seams and welds.
Indoor/outdoor, galvanized members and aluminum posts provide a rigid frame structure, offering long life and maintenance-free operation.
Open plug 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.
Direct drive, TEFC motors are fixed-mounted onto the frame. No belt tensioning or bearing adjustments are necessary. Ultra-compact EC external rotor motor with integral controller.
Peerless' Synergy PLUGlight series is available in Arrangement 4 SWSI.
Arrangement 4 SWSI
Custom Arrangement 4 SWSI utilizes a direct-drive motor mounted onto a base frame. The fan impeller is overhung on the motor and does not need separate bearings.
