Introduction: The Critical Role of Hydraulic Oil Filtration Hydraulic systems power essential functions in construction machinery, from excavator arms to bulldozer blades. However, hydraulic oil contamination—caused by metal wear particles, dust, or moisture—remains a leading cause of component failure. Studies indicate that 70-80% of hydraulic system failures stem from oil pollution, leading to costly downtime and repairs. In high-stakes construction environments, ensuring oil purity isn’t optional; it’s fundamental to operational success.
