What is the minimum required pressure for instrument air?

The minimum required pressure for instrument air is specified to ensure that pneumatic equipment operates effectively and safely. At 200 PSI, this pressure level is typically sufficient to drive pneumatic tools and operate instruments without risking failure or malfunction. This pressure standard helps maintain optimal performance across various systems that rely on compressed air, such as control valves and actuators, ensuring they respond accurately and reliably.

Maintaining instrument air at 200 PSI also allows for compensation of any pressure drops that may occur in the system, ensuring the instruments receiving this air still operate within their necessary parameters. Lower pressures might not sufficiently drive the instruments or may lead to inadequate performance, resulting in potential operational issues or failures. Therefore, aiming for a minimum of 200 PSI is imperative for effective and reliable functioning of air-operated instrumentation.
