FIRMAN T09275 Tri-Fuel Portable Generator

Product Overview

The FIRMAN T09275 Tri-Fuel Portable Generator is an industrial-grade, ultra-versatile power station designed to provide maximum energy security. By offering the ability to run on gasoline, propane (LPG), and natural gas (NG), this generator ensures that you have a viable power source regardless of fuel availability. With a robust 459cc engine and a massive 9-gallon gasoline tank, it is engineered to serve as a high-output solution for whole-home emergency backup, extensive construction sites, or demanding agricultural projects.

The T09275 is built for reliability, featuring FIRMAN’s "Power Stream Alternator" for efficient energy delivery and a cast-iron sleeved engine for extended durability. Safety is prioritized through the integrated CO Alert system, which automatically shuts the engine down if harmful levels of carbon monoxide are detected, and a low-oil shutdown feature that protects the engine from mechanical failure.
