Construction
Peerless' Industrial Blower A series solves your most demanding industrial air handling applications with heavy-gauge housings, direct or belt drives, lip and flange connections, and meticulously welded steel frames.
Wheel
Our high-efficiency "Peerless" wheel design features precision-fabricated impeller blades that are fully welded to a spun wheel cone, balanced against a CNC laser-cut backplate and cast-iron hub.
Frame
Indoor/outdoor, open-member steel frames with pedestal motor mounts keep drivetrains and wheels in alignment longer than formed sheet frames, resulting in longer maintenance intervals.
Housing
All fan housings can be fully rotated to reposition the discharge at any of the pre-drilled intervals, allowing for a wide range of installation and ducting configurations. Housing rotation does not require rebalancing.
Connections
Depending on the Arrangement specified, inlet and discharge ducting flange or ducting lip connections are available. See product literature for each model's standard connections.
Finish
Standard paint finish is a baked polyester coating over phosphatize-cleaned steel materials.
Drive System
Configure as either an adjustable pitch V-belt or direct drive, with heavy-duty motor base rails, ground and polished keyed shafts, and self-aligning normal duty bearings.
Industrial Blower A
Arrangements
Peerless' Industrial Blower A series is available in Arrangements 1, 4, 8, 9, and 10 SWSI.
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 4 SWSI
AMCA Arrangement 4 SWSI utilizes a direct-drive motor mounted onto a base frame, attached to the fan housing. The fan impeller is overhung on the motor shaft and does not need separate bearings.
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.

Options
Light fume and particulate-carrying airstreams especially call for performance- and resilience-boosting upgrades, and Peerless' Industrial Blower A series meets the call with the below factory options.
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.
Vibration Rails
For sound and vibration sensitive applications, Peerless can provide spring or rubber-in-shear Vibration Isolation Rails and Isolation Pads.
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.
Anti-Corrosion Finishes
To help protect against the abuse of particulates, greases, and acids, Anti-Corrosion Paint and Finish options can avoid premature housing damage in very aggressive applications.
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.
