Minimum Air Compressor Size

My setup for 30 years has been a 220v craftsman 60 gallon "v twin" oil less compressor (with extension cord to the dryer at one time) and my only complaint is noise. A 220 compressor will outrun a 110 unit and never look back. Cord doesn't even get warm. When my neighbors piss me off I turn it on.

Only time I'd like more compressor is when using ultra cheap die grinder while porting cast iron with abrasive bits. I don't use abrasive anymore lol

Keeps up easily with an old siphon style gun and stupid easy with an HVLP gun. Just wish I could paint as good with the HVLP as I can the siphon DeVilBiss JGA
