Intake air for instrument air compressors shall not be drawn from which source?

The intake air for instrument air compressors should not be drawn from the medical air intake because medical air is specifically designated for therapeutic use in healthcare settings. This air must meet stringent quality standards and be free from contaminants, ensuring the safety and well-being of patients receiving medical treatments.

By using medical air as an intake source for compressors, there’s a risk of contamination or degradation of the air quality that is critical for patient care. Medical air systems are designed to provide a specific purity and pressure, and diverting air from this source could compromise those standards, leading to potential health risks.

In contrast, ducted air is typically filtered and conditioned for general use, air from equipment rooms might not interfere with medical air standards, and outside air can be managed and filtered to meet the appropriate criteria for use in instrument air compressors.
