Hydraulic oil filter element is generally used in hydraulic stations, construction machinery and equipment, machinery and equipment, mining machinery and hydraulic systems. It should be cleaned regularly, because after a period of use, the hydraulic oil filter element will be blocked by stains/wear in the hydraulic system, thus affecting the filtering effect of hydraulic oil/valve body/cylinder/mechanical equipment, so the maintenance equipment should be replaced regularly.液壓油濾芯一般用在液壓站、工程機械設備、機械設備、礦山機械設備、液壓系統中，要做到定期的清理，因為液壓油濾芯在使用一段時間后，會被液壓系統里面的污漬/磨損物堵塞，從而影響液壓油/閥體/油缸/機械設備的過濾效果，所以要定期更換保養設備。
