What is the function of a hydraulic filter?

The function of a hydraulic filter is to remove contaminants from the hydraulic fluid. In hydraulic systems, the fluid often carries small particles, dirt, and other impurities that can cause damage to components such as pumps, valves, and actuators. These contaminants can lead to decreased efficiency, increased wear, and ultimately failure of hydraulic components.

By filtering out these impurities, the hydraulic filter helps to maintain the cleanliness of the hydraulic fluid, ensuring that the system operates smoothly and reliably. This cleanliness is vital for extending the life of the hydraulic components and improving overall system performance.

Decreasing fluid viscosity, increasing fluid temperature, or controlling fluid flow are functions not typically associated with a hydraulic filter. Instead, those functions are handled by other components within the hydraulic system, such as valves, heaters, or pumps.
