What does a filter do in a hydraulic system?

In a hydraulic system, a filter plays a crucial role in maintaining the cleanliness of hydraulic fluid. Its primary function is to remove particulates, such as dirt, metal shavings, and other contaminants from the fluid. This is vital because contaminants can cause wear and tear on various components, such as pumps, valves, and actuators, ultimately leading to system failure or decreased efficiency.

By ensuring that the hydraulic fluid is clean, the filter helps to prolong the life of the hydraulic components and maintain optimal performance of the system. Regularly changing or cleaning filters is essential in hydraulic maintenance practices to prevent issues related to contamination, which can lead to increased maintenance costs or system downtime. This highlights the importance of the filter's role within hydraulic systems.
