Cleanliness of hydraulic cylinder oil

To ensure the service life of the hydraulic cylinder, effective filtration must be installed in the hydraulic system to prevent contamination. The cleanliness of the oil should comply with the ISO4406 standard, and the quality of the filtration should also comply with the corresponding standards in ISO. The level of the filter is required to be implemented according to the actual working conditions of the system, but the minimum requirement is not lower than level 19/15 in ISO4406, which is level 24 μ (β 10 ≥ 75) in ISO4572.
