Key Features
Innovative Engine Design & Rigorous Testing
Generac's G-Force engine lineup is designed for reliability and extended run times in demanding conditions. The engines feature plateau honed cylinder walls and plasma moly rings for cooler operation, reduced oil consumption, and longer life. Rigid construction and added durability ensure long engine life. Pressurized lubrication provides better performance and less maintenance, with up to a 2-year/200-hour oil change interval. Shutdown protection prevents catastrophic engine damage due to low oil or overheating.
True Power™ Electrical Technology
This technology provides superior harmonics and a sine wave form with less than 5% Total Harmonic Distortion (THD), delivering utility-quality power. This enables confident operation of sensitive electronic equipment and micro-chip based appliances, such as variable speed HVAC systems.
