    Does anyone have a clean understanding of the quality of AIR to be suppled to endo scope clean rooms?

    I hear all kinds of talk with the words Medical Air (Med Air) & Instrument Air (IA).

    Both of these have defined meaning to me (i.e. NFPA 99 2012 Edition Definitions)

    FGI: Has a line item with the words ( Medical Air ).

    HOSPITAL STAFF: Are coming back from trade shows and educational seminars with the words ( Instrument Air ). 

    What is the requirement and by WHO ?

    I have been working with the endoscopy processing equipment manufacturers for a few years, and the quality of air that they need is “instrument grade air”, not to be confused with instrument air as described in NFPA 99.

    I am not near my office this week, where I have the exact description of instrument grade air.

    To summarize, less than 1 mg particulate, and less then 3 deg. C dew point.

    I will provide additional documentation when I have time.
