  • Generac (OHVI) Design Maximizes engine “breathing” for increased fuel efficiency. Plateau honed cylinder walls and plasma moly rings help engine run cooler, reducing oil consumption. Because heat is the primary cause of engine wear, the OHVI has a significantly longer life than competitive engines.
  • “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 Superior lubrication to all vital bearings means better performance, less maintenance and significantly longer engine life. Now featuring a 2 year/200 hour oil change interval.
  • Low oil pressure shutdown system Superior shutdown protection prevents catastrophic engine damage due to low oil.
  • High temperature shutdown Prevents damage due to overheating.

*Rating definitions - Standby: Applicable for supplying emergency power for the duration of the utility power outage. No overload capability is available for this rating. (All ratings in accordance with BS5514, ISO3046 and DIN6271).

* Maximum wattage and current are subject to and limited by such factors as fuel Btu content, ambient temperature, altitude, engine power and condition, etc. Maximum power decreases about 3.5 percent for each 1,000 feet above sea level; and also will decrease about 1 percent for each 12° C (10° F) above 15.5° C (60°F).

*Required fuel pressure to generator fuel inlet at all load ranges - 5 to 7 inches of water column for natural gas, 10 to 12 inches of water column for LP gas
For Btu content, multiply ft3/hr x 2520 (LP) or ft3/hr x 1000 (NG)
