Firman - Built to Last

The FIRMAN H03651 generator features 4550 starting Watts and 3650 running watts (4100/3300 LPG). Power is supplied by our Max Pro Series 208cc FIRMAN engine which runs cool and efficient thanks to its Phoenix Fat Head Block. Our Whisper Series muffler keeps the H03651 running at a quiet 67 decibels – well below the standards set by the National Parks Service, and our spark arrester has been approved by the USDA Forest Service. The industry-leading 5 gallon fuel capacity provides a whopping 14 hours of run time, and you can achieve up to 10.5 hours of run time using a standard 20lb propane cylinder. Starting is as simple as the push of a button on the H03651. All of our Hybrid Series Generators run on gasoline or propane fuel, giving you flexibility while out on the road or during an emergency. H03651 comes standard with extended propane hose (5.5ft) for convenience when running off a larger propane tank.

The FIRMAN Volt Lock automatic voltage regulator ensures clean, consistent power output from the FIRMAN Power Stream alternator. For the ultimate in portability the H03651 includes a wheel kit featuring 8" never-flat wheels and a u-shaped padded handle with ergonomic grip. Pertinent information is at your fingertips with our 3-in-1 data minder measuring Volts, Hertz, Hours and a low oil indicator. The durable, compact tubular roll cage frame design is built for years of use. Everything you need comes standard in the box including: oil, funnel, owner's manual, spark plug wrench, and two wrenches to remove protective shipping brackets.
