What could be a reason for a decrease in the efficiency of pneumatic components?

A decrease in the efficiency of pneumatic components can indeed be attributed to contamination in the air supply. When the air that powers pneumatic systems contains impurities such as dirt, moisture, or oil, it can adversely affect the functioning of the components. Contaminants may obstruct airflow, cause wear and tear on moving parts, or lead to corrosion within cylinders and valves. This, in turn, results in sluggish performance, increased energy consumption, and potentially costly repairs or replacements due to damage over time.

Appropriate air quality is crucial for optimal performance; therefore, ensuring that the air supply is clean and free from contaminants is essential for the overall efficiency and longevity of pneumatic systems. Regularly checking and maintaining the air supply will help alleviate many issues related to decreased efficiency.
