For sale is a Sullair Model 128-50L, 50 HP Rotary Screw Type Air Compressor. Serial No.003-S9910. Rated output air pressure: 100 PSI. Maximum air pressure: 110 PSI. 3/60/460V AC Incoming power. Comes with Pure-Air filtration system (see photo). We did power it, it does run and pump air, but we have a too small 240->460 transformer on a small panel, so we could not run it for long. But it seems fine. Comes from a closed down Caterpillar mining products factory, and as you can imagine, Caterpillar takes good care of their stuff and pays servicers big $$$$$$$ to keep equipment in top shape. 44,000 hours. We can DELIVER and PUT IN PLACE at your location, near Chicago, for an ADDITIONAL fee. I also have a Sullair Air Dryer for sale.
