The FIRMAN T08071 tri fuel generator is a 10000 starting watt trifecta with the ability to run off of gasoline propane and natural gas with an electric starting system. Including a 5.5ft LPG hose for convenience using larger tanks the T08071 is also California emissions certified. It runs at 74dB. Our Max Pro Series 439cc engine runs cool and efficient thanks to its Phoenix Fat Head Block. With a builtin wheel kit and folding handle the tri fuel T08071 can go anywhere and perform however you like.
