Not many motors or compressors like starting under load.

I've known of people (like me) to use refrigerator
compressors as air compressors. There are a few technical
things, like change the oil. A quiet running refrigerator
compressor works nicely, if you start it with zero back
pressure.

A compressor out of a HVAC unit might work, also.
