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 12 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.

Runs all of my "high power" items in the house at the same time!

I have a few things to share about this generator. I have owned a HF Predator 4000w (gas only) for about 6yrs now and have wanted to upgrade to a larger unit for a while. I could run most of the things I needed, but really wanted a "whole home" generator that I could run on NG for the simplicity and unlimited runtime. Fast forward to today, when I bought this workhorse! I brought it home, hooked it to the house and fired it up. I turned on all of the breakers and lights/ceiling fans in the house+gas furnace and also turned on the hot water. After about 5 min, you heard her "downshift" when the well pump kicked on. 5 more min and the water heater kicked on - same thing, but she lined back out and chugged on. So, with that said, this generator ran all of the high power items in my house at the same time through the 30a/240 plug and barely flinched. This was running on gas. Next, I switched to NG (I already had a quick connect for my grill). She fired right up, but started chugging after about 30sec. I figured that I didn't have a large enough NG supply line, so I put installing a 3/4" supply on my "to do" list because that was my main reason for buying Tri fuel. Then I hooked up a propane tank - it wouldn't even start! I went into troubleshooting mode bc this couldn't be right with a brand new generator! After going through the instructions multiple times, following them to the point, it still wouldn't start. Finally, I unscrewed the hose slightly and allowed LPG to escape, then tightened it back. She fired right up! Must have been air locked bc it had never been run on LPG. I pulled it back to the house and did the same thing with the NG - she fired right up! I didn't test running the entire house while using LPG or NG, but I have confidence that I will be able to run everything with selective load use. Now, I do have a couple of complaints. 1)This is a HEAVY unit - as expected. The 11" wheels help, but I think foam filled tires would be a better choice. 2)Since I am planning on running primarily on NG because of gas storage and problems related to varnish in the carb and tank, I need to drain the gas tank. There is no EASY way to drain it! I am going to have to disassemble some things to get to the gas line. The instructions say to drain through the carb drain plug - that would take forever! 3)A built in purge button or sequence for running on NG or LPG would help out a lot if this is how I am going to have to start it every time I switch from gas to NG/LPG or hook up the hoses. Overall, I LOVE this thing so far! I have already browsed the catalog for a small "lunchbox" generator for tailgating and found the refurbished section! I would love to demo one of those. Next

I love my Firmans

Have to say it works just as good as my other one same style different model #. Only complaint is it a lot louder than my other unit. Not sure why but way louder...
