PEAK CALCULATED DEMAND IN SCFM BASED ON FREE AIR SCFM @ 50PSI: 0.00
NOTES:
1. The SCFM above is based on a peak OUTLET demand of 50 psi. Air compressors operate at 100 psi. When sizing a
compressor, you MUST figure the compressor capacity for operation at 100 psi.
2. You need to consider several environmental factors when sizing the compressors. These include altitude, intake air
temperature, and relative humidity. Variance among these factors has considerable effect on compressor selection.
3. Air outlets in labs used for analysis, research or teaching should be supplied by a separate compressed air system,
not the medical air system.
Altitude above sea level, ft: 0
Intake air temperature, °F: 60
Relative Humidity: 0%
PEAK CALCULATED DEMAND IN SCFM: 0.00

and highest relative humidity expected.
