Hello Steve!
I have a machine shop with 4 CNC machines and I want to buy a rotary screw air compressor. Right now I'm having a two stage air compressor and its noisy. My question is what is advantage of using a rotary screw air compressor? what is the difference? If I buy it should I buy 3-phase or single phase? 80 gallon tank should be enough? higher the horsepower the better? please give me your advice. Thank you very much!
