What maintenance tasks are essential for pneumatic systems?

Regular inspection and cleaning of filters is essential for pneumatic systems because filters play a critical role in maintaining the functionality and efficiency of the system. Airborne contaminants such as dust, dirt, and moisture can accumulate in filters over time, which may lead to blockages and reduced airflow. This can compromise the performance of pneumatic components, causing issues like pressure drops, inefficient operation, or even component failure. By ensuring that filters are regularly inspected and cleaned, system operators can help maintain optimal airflow, prevent damage, and extend the life of pneumatic equipment.

The other options do not align with best practices for pneumatic system maintenance. Replacing all components annually could be unnecessary and inefficient, as many components may last longer with proper care. Checking only electrical connections ignores the pneumatic aspects and other critical maintenance needs. Adjusting valves at random intervals could result in inconsistent performance and may not address issues effectively, as it lacks a systematic approach to maintenance. Regular inspections and cleaning establish a proactive maintenance routine that ensures reliable operation.
