Here’s my experience: I bought a very very cheap (69 euros 😆 ) 6 gallon air compressor.
Very noisy.
It had 1/4 inch fittings; I changed these with 3/8 fittings and connected with a bigger air hose.
I have an Ingersoll Rand 2130XP impact and it takes off all the 4 wheel lugs without a problem; then I can put the lugs on again and only then the compressor kicks in again.
Only thing I hate is the noise from the compressor…
So if I were to suggest you a good buy, PLEASE chose a belt driven unit, they are VERY quiet and for 300 bucks you can find one , if not new (for 300 euros, not dollars, I can find a new one here, don’t know about there in US) then search for a good used one on craigslist or similar.
I chose a 6 gallon one because of space in my garage, but to preserve your motor I’d go no less of 12 gallons (50 liters) or bigger. I think a 24 gallons (100 liters) is the best for the DIYer.
Belt driven forever! 😆
Live long and prosper (and stay dirty!)
