PowerFoil Blower AF
Construction
Precision continuous welding, computerized bearing selections, and advanced manufacturing techniques assure that your high-volume ventilation needs will be more than covered with Peerless' PowerFoil AF series.
Wheel
Our high-efficiency "Peerless" wheel design features hollow, heavy-gauge airfoil section blades, aerodynamically engineered and fully welded to a spun wheel cone, balanced against a CNC laser-cut backplate and cast-iron hub.
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, open-member steel frames keep motors, drivetrains, and wheels in alignment longer than formed sheet frames, resulting in longer maintenance intervals.
Housing
All fan housings can be factory set at any of eight 45° intervals, allowing for a wide range of installation and ducting configurations. Housings are welded and not field adjustable.
Drive System
The Airfoil Blower series features a V-Belt drive with cast iron adjustable or fixed pitch sheaves, heavy-duty motor base rails, ground and polished keyed shafts, and self-aligning normal duty bearings.

Arrangements
Peerless' PowerFoil AF series is available in Arrangement 1, 3, 8, 9 and 10 SWSI, and Arrangement 3 DWDI.
Arrangement 1 SWSI
AMCA Arrangement 1 SWSI features dual bearings mounted on a base frame, with an overhung fan impeller for use with belt or direct drives. For belt drive configurations, motor positions W, X, Y, and Z are available. Motor supports can be provided in the field or at the factory.
Arrangement 3 SWSI
AMCA Arrangement 3 SWSI utilizes one bearing on either side of the fan impeller (two bearings total), for use with belt or direct drives. For belt drive configurations, motor positions W, X, Y, and Z are available. Motor supports can be provided in the field or at the factory.
Arrangement 8 SWSI
AMCA Arrangement 8 SWSI is comparable to Arrangement 1, however adds a separate motor pedestal at the end of the impeller shaft, allowing for a direct drive installation coupled with dual external bearings.
Arrangement 9 SWSI
AMCA Arrangement 9 SWSI utilizes dual bearings mounted on a base frame, with an overhung fan impeller for use with belt drives. The motor is mounted outside of the frame or pedestal.
Arrangement 10 SWSI
AMCA Arrangement 10 SWSI features a space-efficient, packaged design with an onboard motor mounted within the fan's bearing pedestal.
Arrangement 3 DWDI
AMCA Arrangement 3 DWDI uses a dual-width impeller setup with one bearing on either side of the fan impeller pair (two bearings total), for use with belt or direct drives. For belt drive configurations, motor positions W, X, Y, and Z are available. Motor supports can be provided in the field or at the factory.

Options
Peerless' PowerFoil AF series can be customized with a variety of options to maximize performance, safety, and reliability across a wide range of applications.
Weather Cover
The solid sheet metal Weather Cover installs over the belt drive and motor frame, offering weather protection without the need of a separately constructed penthouse or canopy.
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.
Automatic Outlet Damper
Protecting the fan from backdrafts, rain, and snow, our corrosion-resistant Outlet Damper securely attaches to the fan outlet. Choose from automatic, motorized, or manual operation. Outlet dampers are not available with mesh screens.
Access Doors
For easy inspection and cleaning, bolted Access Doors can be provided around the perimeter of the fan housing. Our gasketed doors can be provided with bolted or quick-release clamp hardware.
Vibration Rails
For sound and vibration sensitive applications, Peerless can provide spring or rubber-in-shear Vibration Isolation Rails and Isolation Pads.
Spark Resistance
For applications where hazardous gases or other ignitable conditions exist, Peerless offers fully Spark-Resistant Construction and explosion-proof motors per AMCA Spark A, B, and C hazard classifications.
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.
Other Accessories
Additional Peerless Airfoil Blower series accessories include inlet vanes, drain fittings, inlet and outlet screens, flanged inlet and outlet connections, heat slingers, and multiple paint and coating finish options.
