What is the function of a filter in a pneumatic system?

In a pneumatic system, the primary function of a filter is to remove particulates and contaminants from the compressed air. This is crucial because impurities such as dust, water, oil, and other foreign materials can significantly affect the performance and longevity of pneumatic components such as valves, actuators, and cylinders. If these contaminants are not filtered out, they can cause wear and tear, blockages, and potentially lead to system failures.

The effectiveness of the pneumatic system relies on clean air for proper operation; therefore, filters are designed to trap these unwanted particles before the compressed air reaches downstream components. By maintaining air purity, filters help ensure smooth operation, efficiency, and reliability of the entire pneumatic system.
