What is a frequent reason for pneumatic system failure?

The choice highlighting contamination of the air supply leading to component wear is a frequent reason for pneumatic system failure because it directly affects the efficiency and longevity of the system's components. Contaminants such as dust, dirt, water, and oil can enter the pneumatic system, causing abrasive wear on moving parts, clogging filters, and reducing the effectiveness of lubricants. These contaminants can lead to increased friction, overheating, and ultimately, component failure. This issue can compromise the entire pneumatic system's performance, leading to costly downtime and repairs.

Maintaining clean air in a pneumatic system is crucial for avoiding these types of failures. This involves regular inspection and replacement of filters and ensuring that all air supply components are free from debris and contamination, which helps ensure the reliability and efficiency of the pneumatic system.
