About this product
This is a BFO 5HP compressor duty motor designed for air compressor applications. It operates as a single-phase AC motor at 230V with a full load current of 21A, delivering 3450RPM. The motor features an ODP (Open Drip-Proof) enclosure, an IP23 rating, and an Insulation Class F, indicating good thermal endurance. It's equipped with a 7/8-inch keyed shaft, measures 2.25 inches in length, and is designed for counter-clockwise rotation, making it suitable as a replacement or upgrade for existing compressor setups.
Our take
If you're looking to replace or upgrade your air compressor's motor, this BFO 5HP model is a solid candidate. The 3450RPM and 5HP rating suggest it can handle demanding compressor tasks with ease. The 230V single-phase operation is pretty standard for heavier-duty home shop or small commercial use. I appreciate the ODP enclosure, which offers basic protection, though it's not sealed against fine dust or direct water spray. The 7/8-inch keyed shaft is a common size, simplifying installation with compatible pulleys. Just be sure your wiring can handle the 21A full load, and remember its CCW rotation.
