i thought i would add one more thing to this thread. between 110v and 220v the only real difference is your amp draw. therefore the 220v unit is best suited for longer runs of wire , that being the only real advantage of using a 220v unit. to run a 110v unit 800 ft. at 5 amps you would need 4 ga. wire , which is 3 different wires for direct burial , at a cost of about 1.50 ft. for all 3 wires , that size wire includes start up amps , not just running amps. a 220v unit 800ft. at 2.5 amps each leg , you would need a 10 ga. wire , at .50 a ft. , at 800 ft, i just got my compresser kit for free.
