Powering Ahead



Generac ensures superior quality by designing and

manufacturing most of its generator components, such as alternators, enclosures, control systems and

communications software. Generac also makes its own

spark-ignited engines, and you’ll find them on every Generac gaseous-fueled generator. We engineer and manufacture them from the block up — all at our facilities throughout Wisconsin. Applying natural gas and LP-fueled engines to generators requires advanced engineering expertise to ensure reliability, durability and necessary performance. By designing specifically for these dry, hotter-burning fuels, the

engines last longer and require less maintenance. Building our own engines also means we control every step of the supply chain and delivery process, so you benefit from single-source responsibility.



Plus, Generac Industrial Power’s distribution network

provides all parts and service so you don’t have to deal with

third-party suppliers. It all leads to a positive owner

experience and higher confidence level. Generac sparkignited engines give you more options in commercial and industrial generator applications as well as extended run time from utility-supplied natural gas.
