Construction
Designed and built for dusty, gritty, and particulate-carrying airstreams at low pressures, Peerless' Radial Blower KE series easily handles your most challenging dirty air demands.
Wheel
Heavy cast aluminum, straight radial blade design that self-cleans during use, maintaining its balance and assuring efficient airflow even in particulate-heavy conditions.
- Heavy-Duty Cast Aluminum.
- Dynamically Factory Balanced.
- Self-Cleaning Design.
- High Efficiency.
Housing
All fan housings can be fully rotated to reposition the discharge at any of eight pre-drilled 45° intervals, allowing for a wide range of installation and ducting configurations.
- 45° Rotation Intervals.
- Factory or Field Repositioning.
- Housing Rotation Does Not Require Rebalancing.
Rotation
Standard clockwise wheel rotation, bottom horizontal discharge position. Other rotations and discharge orientations can be supplied upon request.
- Clockwise Wheel Rotation Standard.
- Optional Counter-Clockwise Wheel Rotation.
Frame
Indoor/outdoor, open-member steel frames keep motors, 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.
Drive System
Direct drive, open ball bearing motors are fixed-mounted onto a welded base frame. No belt tensioning or bearing adjustments are necessary.
- Factory-Set RPM Available.
- Multiple Motor Options.
- Explosion Proof Motor Options.
Arrangements
Peerless' Radial Blower KE series is available in Arrangement 4 SWSI.
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.
- Direct Drive with Overhung Impeller.
- SWSI Type: Single Width Single Inlet.
- No Bearings on Fan.
- Onboard Motor.
Options
With extreme applications in mind, the Peerless' Radial Blower KE series offers multiple options to extend the fan's service life even in aggressive particulate and soil conditions.
Weather Cover
The solid sheet metal Weather Cover installs over the drive and motor, offering weather protection without the need of a separately constructed penthouse or canopy.
- Eliminates Separate Canopy Cover.
- Solid Metal Protection.
- Removable for Maintenance.
Vibration Rails
For sound and vibration sensitive applications, Peerless can provide spring or rubber-in-shear Vibration Isolation Rails and Isolation Pads.
- Reduces Acoustical Impact.
- Isolates Vibration.
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.
- Protects Against Backdrafts.
- Holds Weather Out.
- Corrosion Resistant.
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.
- Combats Very Aggressive Applications.
- Prevents Premature Failure.
- Ideal for Acids and Greases.
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.
- Hazardous Condition Protection.
- AMCA Spark A, B, C.
- Explosion Proof Motors.
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.
- Any Compatible Motor Can Be Provided.
- Domestic or International Frames.
- Special Environment Ratings.
