This is a 2005, 10 hp, 3 phase, 120 gallon rotary screw with a RotorComp D4 air end. This unit was traded into us for a larger rotary screw and has been gone through by our trained staff. If you're in need of a constant air demand, this unit provides 40 cfm @ 100 psi. This is your opportunity to get plenty of air, while saving money at the same time. It is setup for 3 phase 208-230 v power. Call today for availability and pricing.
