Medical air shall be sampled upstream of which component?

Sampling medical air upstream of the source valve is essential to ensure that the quality of the air meets the required safety and purity standards before it enters the distribution system. The source valve is the component that controls the release of medical air from the supply source. By sampling at this point, any contamination or issues can be identified before the air is allowed to pass through other components, ensuring that the entire downstream system receives only air that meets the necessary specifications for use in medical applications.

Sampling upstream of the source valve prevents contaminated air from affecting the integrity of the medical gas system and protects patients who rely on this air for therapeutic purposes. It is a critical checkpoint to maintain the highest standards of care within healthcare facilities.
