Determine medical air compressor source/intake location requirements

Steps

1. Confirm outdoor compressor air intakes must be located above roof level, at least a specified distance from any door, window, exhaust, other intake, or opening in the building (commonly cited as not less than 10 ft) and a specified height above grade (commonly cited as not less than 20 ft) — verify exact figures against the current NFPA 99 edition
2. Confirm outdoor intakes must additionally be kept a greater separation distance (commonly cited as not less than 25 ft) from ventilation exhausts, fuel storage vents, combustion vents, plumbing vents, medical vacuum/WAGD discharges, or any location capable of collecting vehicle exhaust or other noxious fumes
3. Confirm indoor-compressor air sources must not be drawn from a room/space where chemical-based materials are stored or used, and must not be taken from a room with an open or semi-open discharge from a medical vacuum or scavenging system
4. Confirm the fundamental performance requirement: medical air compressors must draw air from a source of clean air meeting NFPA 99 medical air quality criteria (moisture/dew point, oil, particulate, CO limits)
5. Verify exact separation distances against the current NFPA 99 edition text before finalizing compressor room/intake design, since cited figures can vary between editions
