For nearly three decades, Waukesha’s VGF line of engines has consistently performed under extreme conditions in a wide range of power generation, gas compression, and mechanical drive applications.

GE also provides a range of upgrades for the Waukesha products.

Total Fuel Flexibility

Waukesha engines are capable of operating on a wide range of fuels, from 400 to 2,350 BTU/sq.ft., making them work well for a variety of applications.

The World Chooses Waukesha

With excellent tolerance for variable fuel quality that increases output, uptime, and profitability, Waukesha engines are used worldwide.

Designed from the Inside Out

The VGF series of engines is built to deliver continuous output, with industrial strength to handle continuous high rpm up to 1,175 HP (876 kWb).

WAUKESHA VGF 

If you operate within a wide range of stationary and mobile, spark-ignited, gaseous-fueled applications, the durable, compact Waukesha VGF high-speed engines are designed for you.

  • High-altitude turbocharger that allows operating up to 5,500 feet (1,676 meters) on some lean burn models, and up to 5,000 feet (1,524 meters) on some rich burn models.
  • Quick load step capabilities for optimal operation.
  • Versatile fuel pressure configurations; available as draw-through for low pressure, or blow through for higher pressure fuel.
