This unit costs nearly $40,000 new. Very Low hours (161) on this machine. Uses a variety of blasting media including recycled bottle glass. It is complete and ready-to-go. John Deere 74 HP Diesel Turbo-charged motor. On it's own trailer. Built in Houston at MMLJ. I toured the factory to see how it was made and was very impressed. If you look at the website for MMLJ the latest version of the DB500 is not a powerful as this model. The new one uses a 49 HP Kohler motor and has a 185 PSI rotary compressor. This one has a "210 PSI" rotary compressor. Located in Houston. No trades.
