Heavy Duty Onan Gas Powered, Three Cylinder Air Compressor, Navy Surplus. Not for the home owner/hobby shop. Was demobilized and preserved by Navy and has been stored inside ever since. Has a new fuel tank, never hooked up and will need a storage tank. This baby is built to last and with the gas engine, it can be used anywhere. Was going to use it in my shop but never got the shop built. Consider trade for Conex/Shipping Container, Military vehicle, OBO. Winter is coming, I need the room.
