Absolute best of the best, industrial quality machine. It might be a hard sell though, this is not a homeowner grade machine, and any company looking to buy a machine of this size and quality is likely not looking on Marketplace for one. It might be best to reach our to a proper compressor shop to see if they are interested. They will have the customers who would be the most likely buyers, and they will be far more likely to do business with "pros" when buying something this expensive. You never know though, any shop handy enough might build their own if the shop compressor has failed. This is also the perfect machine for a diesel or large gas engine drive. You would need about a 50hp engine to run this to its potential.
