Instrument air sources must be filtered with activated carbon filters and be located upstream of final line filters: True or False?

Instrument air sources being filtered with activated carbon filters and located upstream of final line filters is essential for ensuring the quality and purity of the air supplied to instruments. Activated carbon filters play a crucial role in removing contaminants such as oil vapor, moisture, and other particulates that can affect the performance and reliability of sensitive instruments. By placing these filters upstream of final line filters, any residual impurities are effectively eliminated before they reach the end-use points, which is vital for maintaining the operational integrity of medical equipment and systems.

This practice is standard and necessary in environments such as healthcare facilities, where the integrity of medical gas systems and instrument air is critical for patient safety and equipment performance. Ensuring that the air is adequately filtered before it arrives at the final line helps prevent contamination and potential failures in medical devices that rely on clean instrument air.
