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,
BobH


I wonder if a screw compressor is a good choice? My understanding is a screw
compressor runs constantly, and "unloads" when the air is not needed. Unless
you use allot of air continually is a screw compressor a good choice?
I think Iggy may have a better choice, a good quality, 5-10 HP slow turning,
cast iron, two stage compressor may be a better choice.
