Minimum Air Compressor Size

HVLP turbine setups work well. My former EAA chapter had one for members to use and several homebuilt aircraft were painted with it, and some won awards. They work on 110V but do require at least a 15-20A outlet as I recall. However, I’d look into what it would cost to have an electrician wire in a 220 volt outlet for you. It might be less than you think.
