Greetings,
Compressors usually have compressor duty motors, which are not to be
confused with continuous duty. If you think about the typical duty cycle
of a compressor, they work hard for a while filling up the reservior, and
then stop. During the off phase, they cool down and return to a safe
operating temp.
I know from experience that you can burn out the motor of a compressor if
you let it run too long. This was a big 3-5 hp industrial model too.
