I=E2=80=99ve had the same Craftsman oil-less unit for about 25 years.  The o=
nly repair has been the regulator a couple years ago.  My biggest like is th=
at the air is clean when I use it for painting, biggest drawback is the incr=
edibly high noise level.  I=E2=80=99ve got a shut off valve right at the air=
 output that does a great job of holding the line pressure.  I keep the comp=
ressor on all the time and when I go to use it it has full pressure so avoid=
 start up pressurization racket. =20

Thanks again for all the replies to my original post about my compressor
motor<br>
not working.<br><br>
With all this going on, I have been doing some thinking about having to
buy a new&nbsp; <br>
compressor if I can't get this motor running.&nbsp; That said, this
compressor appears <br>
to come with a 3hp, 4hp, and 5hp motor.&nbsp; I have the 5hp.&nbsp; I
know that when it<br>
comes to getting a new compressor, bigger is better, to the extent of
your budget.&nbsp; <br><br>
1. What is the advantage of the different hp motors.&nbsp; I know the big
advantage<br>
for the 5hp is it runs on 220V.&nbsp; But how does the hp affect the
compressor.&nbsp; <br>
Based on the info in the manual, it appears that all 3 versions have the
same <br>
SCFM specs.<br><br>
My current compressor is an oil lubricated one.&nbsp; <br><br>
2. I see oil-less compressors that supposedly have fantastic specs for

3.&nbsp; Any body have an oil-less compressor?&nbsp; How do you like

They were saying that the biggest advantage for the oil liubes was for
