Hi John,
The oil-less compressors probably are good enough for casual use, but the
ones that I have been around were noisy, probably because they tend to have
aluminum blocks and that they tend to spin at higher RPM than the larger,
heavier cast iron oil-type compressors.
The noise they make also seems more annoying to my ear, anyway. A larger,
slower spinning pump emits noise, of course, but it does not seem as harsh
as the noise from the oil-less compressor that I have heard.
One advantage of the oil-less compressors is that they will not inject oil
into the air supply if you are spraying paint.
FYIW
best,
doug

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=C2=A0 <br>
compressor if I can't get this motor running.=C2=A0 That said, this
compressor appears <br>
to come with a 3hp, 4hp, and 5hp motor.=C2=A0 I have the 5hp.=C2=A0 I
know that when it<br>
comes to getting a new compressor, bigger is better, to the extent of
your budget.=C2=A0 <br><br>
1. What is the advantage of the different hp motors.=C2=A0 I know the big
advantage<br>
for the 5hp is it runs on 220V.=C2=A0 But how does the hp affect the
compressor.=C2=A0 <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.=C2=A0 <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.=C2=A0 Any
thoughts?<br><br>
3.=C2=A0 Any body have an oil-less compressor?=C2=A0 How do you like
it?=C2=A0 I was reading an<br>
article that was talking about how the oil-less versions have come a long
ways.=C2=A0 <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.=C2=A0 But my dad's
compressor,<br>
a 4hp 220V 20 gal unit and my 5hp 220V 30 gal rig were all oil
lubed.=C2=A0 We got dad's<br>
compressor back in the 60s and it was still running when he passed in
2015.=C2=A0 I <br>
bought mine back about '90.=C2=A0 So I lean toward them.=C2=A0 But is
that realistic?<br><br>
