Finer filtration improves the cleanliness level of the hydraulic fluid, which increases the service life of the axial piston unit.
A cleanliness level of at least 20/18/15 is to be maintained according to ISO 4406.
At a hydraulic fluid viscosity of less than 10 mm²/s (e.g. due to high temperatures in short-term operation) at the drain port, a cleanliness level of at least 19/17/14 according to ISO 4406 is required.
For example, the viscosity is 10 mm²/s at:

| Nominal pressure | pnom | see table of values | The nominal pressure corresponds to the maximum design pressure. |

| Minimum pressure | pHP min | 25 bar | Minimum pressure on high-pressure side (port A or B) required to prevent damage to the axial piston unit. |
