Which maintenance practice is recommended for pneumatic systems?

Regularly inspecting and replacing filters is a critical maintenance practice for pneumatic systems because filters play an essential role in ensuring the integrity and efficiency of the compressed air being used. Contaminants like dust, moisture, and oil can significantly affect the performance of pneumatic components, leading to wear, corrosion, and potentially catastrophic failures.

When filters are clean and functioning properly, they help to maintain optimal air quality and system pressure, which in turn enhances the overall reliability and lifespan of the pneumatic system. Contamination can result in erratic operation, increased energy costs, and unplanned downtime, making regular filter maintenance a proactive way to prevent these issues.

In contrast, other practices mentioned do not align with best practices for maintaining pneumatic systems. For example, lubricating pistons only once a year may not be sufficient depending on the application and environment, and ignoring minor leaks can lead to inefficiencies and higher operating costs. Cleaning air intake vents annually may also not be adequate if there is regular exposure to contaminants. Thus, consistent filter inspection and replacement stand out as a fundamental practice to ensure optimal performance of pneumatic systems.
