Wavin Hardenberg

  • Reduce downtime hydraulic system, caused by oil contamination
  • Improve cleanliness levels hydraulic oil / Increase lifetime hydraulic oil

RMF Scope

With standard filtration solutions like Suction, Pressure & Return line filters, the oil cleanliness still exceeds the levels requested by the component suppliers (of servo & prop. valves). The solution for Wavin was to install 31 RMF branded Off-Line Units.


  • Oil cleanliness before Off-Line filtration: ISO 15/12/11, NAS3
  • Oil cleanliness after 3 months of Off-Line filtration: ISO 11/08/00, NAS0
