The G150 mobile generator is a durable, sound attenuated generator that provides mobile, prime power for larger applications requiring quiet reliable power. The T4i models are especially suited for areas requiring BAT (Best Available Technology) to meet the most stringent EPA, CARB air standards. A digital controller monitors and protects the generator and engine while providing continuous operating data on an easy to read LCD display. Large fuel tanks provide long running times.
