The Part That Finishes the Job, In Stock

Squirrel Cage Blower Wheels and Run Capacitors, Matched at the Counter
Blower wheels are the classic stall: dozens of diameters, widths, bores, and rotations, and the wrong one vibrates itself apart. Bring the old wheel or its measurements and we'll match it, squirrel cage or paddle.
Same with motor run capacitors: µF rating, voltage, and shape all matter. Our staff can read your motor's requirements off the nameplate and hand you the right capacitor with the mounting kit to go with it.
