This 3.7 HP electric motor is a powerful replacement for air compressors and other heavy-duty equipment requiring high startup torque and sustained power. With 3450 RPM speed and built for compressor-duty applications, it’s designed to keep up with continuous use in demanding environments like workshops, garages, and industrial settings.

Engineered with a standard 56 frame, it includes a 5/8" shaft diameter, 2-1/2" shaft length, and a 3/16" keyway—making it a compatible fit for most compressor mounts with no modifications required. Its non-reversible counter-clockwise (CCW) rotation, when facing the shaft, ensures proper compatibility for fixed-direction applications.

Powered by 230V single-phase electricity and rated for continuous duty, this motor includes manual reset thermal overload protection for peace of mind during extended run times. The Open Drip Proof (ODP) enclosure ensures ventilation while maintaining internal protection in standard operating environments.
