Key Benefits


  • GreenOil systems clean oil more effectively than even the best centrifuges
  • Short return on your investment, typically within 6 - 10 months
  • 8 - 10 times less energy consumption than a separator
  • No sludge production – no wasted oil, savings from no disposal
  • Clean oil, secure operational reliability and durability!


The necessity for absolutely clean oil is commonly known as good practice. Downtime and repairs may be reduced 5 - 10 times for hydraulic systems, 4 - 8 times for lubrication system oils and oil lifetime may be prolonged by 4 - 8 times. Improved filtration is thus vital to reduce cost, repairs, and downtime. The unique combined GreenOil filter yields a new top class standard for particle filtration.
