I have a Mattie 20 hp rotary screw air compressor. it's a 129 cfm! I hooked it up and it pumps pleanty of air. it's a little bigger than I want. I also do not have access to three phase at my house but I will give your money back if you have any problems making it work. Make me a reasonable offer. Mattie still sales this model. A new one will cost you around 9,000 plus tax and shipping. This is a good used unit! It was removed and replaced by two larger compressor. This compressor was just outgrown by the number of new CNC machines. Don't be shy throw out some offers it might surprise you on what I'll take for it. I'm looking to use any prophet to buy some communal hand tools for work.
