I'm in agreement with Bentrim (above). Biggest problem with oil-less is they don't seem to be designed to last very long or survive much more than casual, occasional use. I've had several on which the reed valve was broken or cracked so they wouldn't make or hold pressure, and there are no parts available, so the only thing left is the scrap heap.
Another problem on ALL compressors is that nobody (except us, of course) ever drains the water out of the tanks and they rust. You do not want to have a tank burst because of rust perforation - that's a *lot* more excitement than we bargained for.
So here's my spec list for the "ideal" compressor (YMMV). 1 - The compressor body should be cast iron and HAVE oil, that way it will last a long time. 2 - Aluminum tank - no corrosion and lighter so I can move it around fairly easily. 3) Minimum 25 gallons, better 40 gallons, I want the capacity. 4 - Vertical tank to save floor space. 5 - motor and compressor are separate units so can be replaced individually. 6 - 1,750 RPM - QUIET please. 7 - 110v so I can move it around in my hangar and not have miles of hose strung everywhere. 220 volts will be OK once an air distribution system is in so I won't have to move the compressor any more. Then it gets a small, removable enclosure with sound deadening material.
This will feed an air distribution system along one wall of my workshop. I was going to use black pipe, but I was in a big-bucks-cost-no-object boat manufacturer, and they used the aluminum (blue pipe) system that Summit, eBay, Amazon and others sell for about $300 or so. They're a billion dollar business (not an exaggeration) and if that system works for them, I strongly suspect it will work for me. (When I make my first billion, I'll have my compressor gold plated.)
Until I set that up, I'm using a 20 gallon Craftsman "has-oil" compressor connected to its 110v motor with a v-belt. I've owned it over 40 years, it just keeps soldiering along, with proper maintenance of course. I am starting to get a bit nervous about tank corrosion, so I stop it at 80psi which is adequate for everything I do.
That takes care of air-intensive jobs, working on cars, air drills, paint work (maybe, I have an HVLP system that doesn't use compressed air).
I also have a small, portable compressor that gets used to fill tires and on small jobs outside of the workshop.
Best regards and have a happy and safe new year!
