I have an 80-gallon Ingersoll Rand, which is a 2 phase compressor.I have had several 30 gallons over the years, some oil less, and an oil compressor. I recommend at least a 60-gallon or larger if you detail a lot, to be able to keep up with sanding as well as blowing vehicles out with compressed air, etc. A 30 gallon will do the trick for the most part, but you will need to give the compressor a break so it can catch up and refill the tank, every so often. With an 80 gallon, you can run just about anything you need. I upgraded close to 10 years ago and would not want to go back. However, most 60s and pretty much all 80s need to phase power to run. Hope this helps...
What type of air compressor are you running??
