What does a filter do in a fluid power system?

In a fluid power system, the primary function of a filter is to remove contaminants from the fluid. Contaminants may include dirt, debris, metal particles, and other impurities that can compromise the performance and reliability of the hydraulic or pneumatic system. By filtering out these unwanted particles, a filter helps maintain fluid cleanliness, which is critical for the longevity of components such as pumps, valves, and actuators. This cleanliness helps prevent wear and damage to the system, ensuring efficient operation and reducing the likelihood of failures or maintenance issues.

Maintaining proper fluid cleanliness through filtration ultimately contributes to system efficiency and effectiveness, allowing the system to perform optimally without the risk of contamination-related problems.
