Default Buying a used air compressor: tips?

Is there any reason to believe that these motors have different
characteristics than other cap start cap run motor (which is what this
motor is)?
Is there a reliable source that says compressor motors have a different
characteristic?
That is, is there any reason an honest company wouldn't use the real HP?

Perusing the Grainger catalog (real paper), many of the smaller
compressors (maybe 6HP max) have a "peak HP" and a "run HP". Peak HP was
what was used by companies that were sued in the class action. It is
likely what "SPL" is. "Run HP" is the mechanical HP used at the rated
air output (the real HP). "Run HP" generally ranges from about 30 to 65
% of "peak HP". In general the higher the HP the lower the percentage.

The companies in the class action presumably agreed to not mislabel
their compressors. That puts them at a disadvantage to companies like Jon's.


No ****, sherlock, what you think I have been trying to explain for the last
two days?


It started when gfretwell said 1HP was about the max you could run on a
15A circuit. You said "nonsense" you run your 3HP motor on a 15A
circuit. In the quote above clare told you it is not a 3HP motor. That
is what everyone else has been telling you.

Then you said it was a 2.3HP motor - also wrong.

Nobody seems to know what you are saying, including you.
