PowerFixed 2000 Blower BI/BC

Construction

Built for dependability and bare-minimum maintenance, Peerless' PowerFixed 2000 BI/BC series combines heavy-duty fabrication techniques with advanced engineering design for medium and high-pressure applications.

BI and BC Designations

The BI and BC designations both refer to flat blade, backward inclined, belt drive assemblies. The BI range offers small, lower pressure versions, while the BC range provides higher volume, higher pressure performance.

BI Wheel Diameters 10.5 to 24.5".
BC Wheel Diameters 27" to 49".
Higher Static Pressures Than Airfoil Blades.

Wheel

Peerless' highly efficient flat blade wheel uses die-cut blades that are fully welded to a spun wheel cone, balanced against a CNC laser-cut backplate and cast-iron hub.

Die-Cut Flat Blades on All Models.
Dynamic Factory Balanced.
Aerodynamic Spun Cone.
Riveted Back Plate.

Inlet

For low-turbulence inlet airflow and balanced rotation, our inlet cones are stamped or rolled from single sheets, free of seams and welds.

Rigid Streamlined Inlet.
Single-Piece Construction.

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.

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.
BI Models offer Factory or Field Repositioning.
BC Models offer Factory Positioning Only.
BI Housing Rotation Does Not Require Rebalancing.

Drive System

The Backward Inclined Fan series features a V-Belt drive with cast iron adjustable pitch sheaves, heavy-duty motor base rails, ground and polished keyed shafts, and self-aligning normal duty bearings.

Adjustable Motor Base for Belt Tensioning.
Factory-Set RPM Available.
Multiple Motor Options.
100K Run Hour Bearings.

PowerFixed 2000 Blower BI/BC
