About this product
This BFO 3.7 HP air compressor motor is a single-phase, 230V unit designed for continuous compressor duty. It features a 56-frame, base-mounted design with a 5/8 inch keyed shaft (1.88 inches long) and a 3/16 inch standard size keyway. Operating at 3450 RPM, it has an Open Drip Proof (ODP) enclosure, an F insulation class, and a 1.0 service factor. It's manufactured in China and comes with a 1-year warranty.
Our take
This 3.7 HP motor from BFO is a solid option if you need a dedicated 230V single-phase replacement for your air compressor. The continuous compressor duty rating and 3450 RPM indicate it’s built for sustained operation. The 56 frame and 5/8-inch keyed shaft are standard, which should simplify installation as a direct replacement. However, it's an Open Drip Proof enclosure, so placement in a dry, protected area is crucial. While it comes with a 1-year warranty, the 'No Instruction Included' note means you'll need some mechanical knowledge for installation.
