Need a new air compressor

Scroll compressors kick butt. They are made for high volume and typically do not use a tank. We have several HUGE ones at work. One we use to blow out a 12" diameter, 1 mile long pipeline. The problem with most of the scroll compressors is they are three phase. 7.5hp is about the biggest you can go single phase....maybe 10.
That 5hp quincy above is a good buy for what you get. More than enough for most homeowner shops. I opted for the 7.5 with the max package but honestly that 5 probably would have been more than enough.
