Hydraulic fluid Mineral oil (HL, HLP) according to DIN 51524. Other hydraulic fluids, such as HEES (Synthetic Ester) according to VDMA 24568.

Hydraulic fluid temperature range(℃ ) -20 to +90 Viscosity range ν (mm2/s) 10 to 380 Maximum permissible degree of contamination of the pressure fluid cleanliness class to ISO 4406 (C)

Class 20/18/15, we therefore recommend a filter with a minimum retention rate of β10 ≥ 75
