Features and Benefits:

• Engine
  • Generac G-Force design: Maximizes engine “breathing” for increased fuel efficiency. Plateau honed cylinder walls and plasma moly rings help the engine run cooler, reducing oil consumption and resulting in longer engine life.
  • “Spiny-lok” cast iron cylinder walls: Rigid construction and added durability provide long engine life.
  • Electronic ignition/spark advance: These features combine to assure smooth, quick starting every time
  • Full pressure lubrication system: Pressurized lubrication to all vital bearings means better performance, less maintenance, and longer engine life. Now featuring up to a 2 year/200 hour oil change interval.
  • Low oil pressure shutdown system: Shutdown protection prevents catastrophic engine damage due to low oil.
  • High temperature shutdown: Prevents damage due to overheating.
• Generator
  • Revolving field: Allows for a smaller, light weight unit that operates 25% more efficiently than a revolving armature generator.
  • Skewed stator: Produces a smooth output waveform for compatibility with electronic equipment.
  • Displaced phase excitation: Maximizes motor starting capability.
  • Automatic voltage regulation: Regulating output voltage to ±1% prevents damaging voltage spikes.
  • UL 2200 listed: For your safety.
• Transfer Switch (if applicable)
