For sale is an Eaton, Polar Air, 30hp Industrial Air Compressor. This unit was running our plant up until a few weeks ago. It is a bit dirty but a solid unit. We replaced this unit because the variable speed drive is starting to fault out more regularly. Once we reset the drive (only takes a couple min) it would run fine for another day or two. It wasn't working in our application anymore because we run 24/7 and need something more reliable. So for a smaller shop or a non 24/7 application this unit might work fine. The motor is solid and the internal tank was just repaired.
