I am looking at replacing my old shop air compressor and have been
looking at the rotary screw type compressors because they are quiet.
They are a lot more money than a piston type compressor. The smallest
ones I have seen are 5HP which would be about the right size for what I
want.

Does anybody whether they output clean air or is there a lot of oil to
be removed?

Would I need to run a big filter and refrigerated dryer to paint or use
a plasma cutter?

Thanks,

Unless your going to turn it on and run it for hours straight you will not
be happy with one. They are made to run, most are 7X24 type machines. I
was going to get one before I looked into one. For a plant or high volume
user they are GREAT. For a home shop they are not the ideal setup. They
don't normally cycle on an off they run and unload so they stay running the
whole time you need air and then some. The GD model I was looking at was a
super nice unit but it's MIN run time was 15 min. ( so if it turned on 4
times under light use it would run for a hour) and it was really designed to
be turned on that the start of the shift and off at the end..
