Our take
This 3HP electric AC motor looks like a strong candidate for anyone needing to replace or build an air compressor. The single-phase 115V operation makes it suitable for standard residential or workshop power. With 3450 RPM and 2.2KW input, it offers good power for demanding applications. I appreciate the durable steel plate and aluminum construction, suggesting longevity. The IP23 rating indicates some protection against solid objects and water, which is a plus. While the 68dB noise level isn't silent, it's reasonable for a motor of this power. Be sure to check that the 5/8-inch shaft diameter and CCW rotation match your existing setup.
