Medical air supply should meet the following requirements: a medical air prohibited for non-medical purposes; 2, medical air cylinders or air compressors can be supplied; 3, medical air and instrument air compressor group shared air compressor air The moisture content should conform to this specification table 3.0.1 relevant provisions of the instrument air. Medical air supply emergency backup power source should be set to the process gas water quality indicators: water vapor content in compressed air compressed air filters, pressure dew point characterization. In order to prevent condensation of water in the presence of system, dew point temperature is generally advisable after drying gas pipelines and gas equipment compressed air, coupled with the lowest temperature likely to be encountered -5 ~ -10 ℃. Other indicators: pressure and temperature and other indicators of the same with the conventional design. Design supply quality indicators: 1 RSP: process gas ≥0.5μm, 100 级; gas meter ≥1μm, 100 levels. 2 pressure dew point: ≤-20 ℃, the same process and instrument air. 3 Total oil content: ≤0.01mg / m3, the same process and instrument air. 4 biological particles ≤1CFU / m3, considering only the process gas.
