Using environment
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 (℃) Class 20/18/15, we therefore recommend a filter with a minimum retention rate of β10≥75
