Wanting to size a portable air compressor. How many cfm’s do I need for max thickness?

I bought one in May and returned it because it was 110v with a 220v adaptor. I contacted them and they appeared to say, in broken English, that more 2nd gen would be available in June, which I assume will be the preferred power cord configuration. Still waiting...........
