Introducing the FIRMAN T09371, the most powerful tri-fuel portable generator in our hybrid lineup. Designed to run on gasoline, propane (LPG), or natural gas (NG), this versatile powerhouse delivers up to 11,600 starting watts and 50 amps at 120/240V—making it the ultimate solution for heavy-duty jobs, emergency backup, and home standby power. Engineered with the Max Pro Series 459cc engine and the durable Phoenix Fat Head Block, the T09371 runs cool and efficiently, even under demanding loads. It operates at just 74 dB and is emissions-certified in 49 states and Canada, combining power with environmental responsibility. CO Alert technology ensures safe operation by automatically shutting down the generator if unsafe carbon monoxide levels are detected. Equipped with a 9-gallon fuel tank, the T09371 provides up to 11 hours of runtime at 50% load. The generator features a 4-in-1 data minder to track volts, hertz, runtime hours, and low oil levels, keeping you in full control. Transport is easy thanks to its rugged frame, 10” wheels, and fold-down handle. This model comes ready to power your world, offering a wide range of outlet types: one 120V 20A GFCI duplex outlet (5-20R), one 120V 30A twist-lock (L5-30R), one 120/240V 30A twist-lock (L14-30R), and one 120/240V 50A outlet (14-50R).
