Twin air compressor.
This compressor is amazing! It flows more air than my 30gal oiled shop compressor. The twin motors run so smooth and fairly quiet. The only modification I made was adding an inline air dryer because of the large amount of after that starts spraying out after a minute. It fills my 285-70-r17 tires from 20-60psi in only 18 minutes. The air hose and air gun work great. I love that it has a 100% duty cycle. I have no problems with it killing my 6.7l dodge ram batteries with the engine off. I’d say it worth the price tag.
