What is the required dew point for instrument air systems?

The required dew point for instrument air systems is critical for ensuring the effective operation of the instruments that rely on this air. A dew point of -40°F is essential because it minimizes the presence of moisture in the air system. High levels of moisture can lead to corrosion, freezing of components, and malfunctioning of sensitive instruments. Maintaining a dew point at -40°F or lower helps to ensure that any moisture in the compressed air remains in vapor form and does not condense into liquid, which can damage equipment and affect performance. This standard is crucial across various industries, particularly in environments where precision instrumentation is vital, such as in healthcare or manufacturing.
