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 <br>
compressor if I can't get this motor running. That said, this
compressor appears <br>
to come with a 3hp, 4hp, and 5hp motor. I have the 5hp. I
know that when it<br>
comes to getting a new compressor, bigger is better, to the extent of
your budget. <br><br>
1. What is the advantage of the different hp motors. I know the big
advantage<br>
for the 5hp is it runs on 220V. But how does the hp affect the
compressor. <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. <br><br>
2. I see oil-less compressors that supposedly have fantastic specs for
air supply<br>
that are so much cheaper than oil lubed versions. Any
thoughts?<br><br>
3. Any body have an oil-less compressor? How do you like
it? I was reading an<br>
article that was talking about how the oil-less versions have come a long
ways. <br>
They were saying that the biggest advantage for the oil liubes was for
high air<br>
demand over a long time like in a commercial shop. But my dad's
compressor,<br>
a 4hp 220V 20 gal unit and my 5hp 220V 30 gal rig were all oil
lubed. We got dad's<br>
compressor back in the 60s and it was still running when he passed in
2015. I <br>
bought mine back about '90. So I lean toward them. But is
that realistic?<br><br>
