Why should a pneumatic system be purged periodically?

Purging a pneumatic system periodically is essential to remove contaminants such as moisture, dirt, or oil from the system components. Over time, these impurities can accumulate and lead to corrosion, reduced efficiency, or even failure of pneumatic components. Moisture is particularly problematic as it can freeze in cold environments, obstructing airflow and causing malfunctions. Maintaining clean and dry conditions within the pneumatic system ensures that it operates smoothly, prolongs the lifespan of components, and maintains operational safety and reliability.
