About this product
This is a 5 HP electric motor specifically designed for air compressor applications. It operates at 3450 RPM with a 60 Hz AC frequency and accepts a nominal input voltage of 208-230V, single-phase. The motor features a 7/8 inch keyed shaft with a 2.25-inch length and an Open Drip Proof (ODP) enclosure type, providing basic protection against vertical drips. It's base-mounted and non-reversible, making it suitable for dedicated air compressor use.
Our take
For those in need of a replacement motor for their air compressor, this 5 HP unit offers robust power at 3450 RPM, which is standard for many compressor applications. The 208-230V single-phase input means it's suitable for a range of workshop or light industrial electrical systems. The 7/8-inch keyed shaft is a common size, simplifying compatibility with existing pulleys. While the Open Drip Proof (ODP) design is adequate for dry environments, it's worth noting that it offers less protection against dust or moisture than a Totally Enclosed Fan Cooled (TEFC) motor. The 1.0 service factor also indicates it's not designed for continuous overload.
