What is generally a sign of a malfunctioning pneumatic system?

A sign of a malfunctioning pneumatic system is often indicated by sudden noises during operation. These noises can signify various issues within the system, such as leaks, internal component failure, or mechanical friction. When the system is functioning properly, the operation tends to be smooth and quiet, with normal pressure levels and consistent flow rates. Any sudden or unexpected sounds can serve as an alert that further investigation is needed to determine the root cause of the malfunction. This makes monitoring operational sounds an essential part of maintaining the health of a pneumatic system.
