Why is periodic purging of a pneumatic system necessary?

Periodic purging of a pneumatic system is vital for removing moisture and contaminants that can accumulate over time. These impurities can adversely affect the efficiency and reliability of the system. Moisture in particular can lead to corrosion of components, freezing in cold environments, and reduced effectiveness of the pneumatic tools and equipment being supplied by the system. Therefore, regular purging helps maintain optimal operating conditions and prolongs the life of the pneumatic system.

While factors such as checking for leaks, increasing system pressure, or replacing old air with new air may be considered in maintenance routines, the primary purpose of purging is directly associated with the removal of accumulated dirt, oil, and moisture, ensuring that the air supplied remains clean and dry for effective system performance.
