What is the primary purpose of a filter in a hydraulic system?

The primary purpose of a filter in a hydraulic system is to remove small contaminants from the fluid. Contaminants can include dirt, rust, metal shavings, and other particulate matter that can cause wear and damage to hydraulic components such as pumps, valves, and actuators. By effectively filtering out these contaminants, the filter helps to maintain the cleanliness of the hydraulic fluid, which is essential for the efficient and reliable operation of the system.

Keeping the hydraulic fluid clean reduces the risk of clogging, extends equipment life, and supports consistent performance. This filtration process is crucial because it minimizes the potential for system failures and costly repairs, ultimately ensuring that the hydraulic system operates smoothly and effectively.
