That’s likely not going to provide adequate performance to run things like impacts or air drills. I think a typical 1/2” impact will pull 5 or 6 CFM so you’ll likely be pushing maybe 45 or 50 psi through it effectively cutting its performance in half. I could be wrong as my brain isn’t functioning well today.

Also, as to your original question, I would avoid going with large diameter hoses or fittings for fear of really outpacing your rated cfm.

Also, not to be a total negative Nancy, but everyone that I know who’s had one of those oil-less compressors hasn’t gotten much use out of it before it cratered. Hopefully you’ll have better luck.
