The single phase we have on a 220v 40A circuit.My data sheet says 17 FLA.?

The bigger version is 3-phase, which I would have bought but back in the day we had no other 3-phase equipment in service and didn't want to pay for it. Hindsight is 2020....

I’m definitely looking at that Eastman. Is that 220v single phase? What’s the draw?

Eastman 30/60 going?on years now - 5+, can't remember, never had an issue other than external pressure switch required replacement after a reasonable duration for $20 or so. You can probably search my remarks when the topic has come up in the past. It has consistently output the best quality air for our spray finishing and with Shopsabre?IS408 10hp w/ATC, as well as wide belt sander. We have added air receiver tanks to add surge capacity beyond the 100% duty cycle the machine offers for the wide belt's?excessive?blow-off input - it's a Chicago-style? fitting if that gives any indication. It's been terrific, and quiet, and I'd do it all over again.

If I needed more than what one unit could maintain, I'd put multiple scrolls in parallel for added capacity as needed up to the point a screw made more sense, but that's hard to imagine in a normal small woodshop unless you are sandblasting or running multiple air sanders shift-worker style. Screws need to run and are bad at cycling. Scrolls don't care.

My shop Sabre needs 9 @ 100 psi for spindle and ATC. CamMaster is similar. Don’t cheap out on the compressor. I already had a noisy IR 5hp comp when I got the cnc. I’m definitely getting a scroll comp asap because the IR is damn loud.?

I have the Sli-Air with 3 pumps, not 6. It works to run my cnc mill for tool changes and a mist coolant system. If the machine you are looking at has continuous spindle purge to keep dust out of the bearings. it might need a decent amount of air.... but 7cfm at 110 psi sounds a bit extreme. I'd ask other users of the same machine, not the salesman that is just going to blurt out a safe, if over kill amount.

That's just what the rep told me to shop for when I was at IWF last week. My understanding is that it uses air for tool change as well as some cooling of the spindle. I'm guessing that leaves some safety margin. I did lookup some of the older threads to get some ideas. I think someone was recommending sil-air units for quietness, the closest I found that I think has the recommended CFM would be this maybe, ? A bit pricey but might be worth it, the only other thing I need air in the shop for is Mac's clamps that I have on order.
