" And I think that air compressor chart that Sears provides in its
Craftsman catalog is misleading then, since many grinders, drills, etc.,
take 13-15 SCFM, and the chart claims their 60 gal. compressor will run
those air tools continuously, even though the SCFM output is only around
9.6! That's why I was comparing the Sears 7.0 HP 60 gallon one above with
the IR 5 hp 60 gallon one, even though the output was really different!



Keep in mind that you will rarely run air tools constantly. I have a 10
CFM compressor and it does all I need. I also use air drills, DA sanders
and die grinders. 10 CFM will run any of the tools I have as most people
will not run them 100%. Sears claim is probably accurate for the general
population. Unless you plan on using your air tools to the extreme, you
will probably be satisfied with a 10 CFM compressor.


Thanks Greg! This is a good point. The thing is, I would like to have the
option to run a grinder or sander or paint gun for 2-3 minutes continuously,
and I don't know if the Sears 9.6 scfm would cut it. Plus I would worry the
motor would be running continuously trying to keep up with me, thus leading
to premature failure.

That said Sear's compressors are junk. If you can afford a larger
compressor, go with it, it will live longer because it will not run as
hard. If you can afford the IR, buy it, you will never replace it!

Thank you! I'm looking forward to buying an IR one then as everyone here
seems to agree that Craftsman is junk.
