What negative effect can moisture have in a pneumatic system?

Moisture can have significant detrimental effects in a pneumatic system, primarily by causing rust and corrosion. When moisture is present, it can accumulate in components such as cylinders, valves, and air lines. This accumulation leads to the formation of rust on metal surfaces, which can severely impair the functionality of the system. Rust and corrosion create rough surfaces that increase friction, potentially leading to more significant wear and tear on components, leaks, and ultimately system failure.

In contrast, options related to increasing operational speed, enhancing component efficiency, or improving air filtration do not reflect the reality of moisture's impact. Instead, they suggest positive outcomes that are not associated with the presence of moisture in pneumatic systems. Hence, the recognition of moisture as a catalyst for rust and corrosion emphasizes the importance of maintaining dryness in pneumatic applications to ensure reliability and longevity.
