Maximum admissible degree of contamination of the hydraulic fluid, cleanliness class according to ISO 4406 (c) 1)Class 20/18/15
1)The cleanliness classes specified for the components must be adhered to in hydraulic systems. Effective filtration prevents faults and simultaneously increases the life cycle of the components. For the selection of the filters, see www.boschrexroth.com/filter.

Important information on hydraulic fluids:

  • For more information and data on the use of other hydraulicfluids, please refer to the data sheets above or contact us.
  • There may be limitations regarding the technical valve data (temperature, pressure range, life cycle, maintenance intervals, etc.).
  • The ignition temperature of the hydraulic fluid used must be 50 K higher than the maximum surface temperature.
  • Flame-resistant – containing water:
  • Due to increased cavitation tendency with HFC hydraulic fluids, the life cycle of the component may be reduced by up to 30% as compared to the use with mineral oil HLP. In order to reduce the cavitation effect, it is recommended – if possible specific to the installation – to back up the return flow pressure in ports T to approx. 20% of the pressure differential at the component.
