Industrial Blower A

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.

Flat Blade Backward Inclined Wheel.
Dynamic Factory Balanced.
Clockwise or Counter-clockwise Rotation.
15,000 FPM Wheel Tip Max Speed.

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.

Fully-Welded Steel Frame.
Easy Maintenance Access.
Fewer Alignment Adjustments Needed.

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.

Factory or Field Repositioning.
A-9 to A-17 have 22.5° Intervals.
A-19 to A-23 have 15° Intervals.
A-26 to A-33 have 11.25° Intervals.

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.

Ducting Flange and Lip Connection.
Check Literature for Standard Connections by Model.

Finish

Standard paint finish is a baked polyester coating over phosphatize-cleaned steel materials.

Highly Durable Polyester Coating.
Steel is Cleaned and Prepped Prior to Coating.
High Abrasion Resistance for Long Life.

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.

V-Belt or Direct Drive.
Factory-Set RPM Available.
Single Speed, TEFC, Inverter Duty Motor.
