Manufacturer overview

*Available At Lowes.com The FIRMAN T08073 Tri-Fuel Hybrid Generator offers exceptional versatility and serious performance, making it a storm-ready solution. Designed to run on gasoline, propane (LPG), or natural gas (NG), it delivers up to 10,000 peak watts and features a 50A 120/240V outlet—perfect for powering essential appliances, tools, or an entire home during an outage. At the core is FIRMAN’s Max Pro Series 459cc engine, paired with the durable Phoenix Fat Head Block for cool, efficient operation. Safety is built in with CO Alert, which automatically shuts the generator down if dangerous carbon monoxide levels are detected. Despite its power, the T08073 operates at just 72 dB, and features an electric start for effortless ignition. It’s emissions-certified in 49 states and Canada, giving you reliable power wherever you are. With a large 8-gallon fuel tank, it runs for up to 10.5 hours, and includes rugged features like a roll cage frame, 11” wheels, and a folding handle for easy transport. A wide array of outlets—including a 50A plug, multiple 30A ports, and a GFCI-protected 20A duplex—ensures maximum flexibility for home, jobsite, or RV use. Every T08073 comes with bonus accessories: a cover, power cord, oil, funnel, spark plug wrench, and operator’s manual—all backed by FIRMAN’s 4-year warranty.
