*1 Converted value assuming the integrated flow quantity under the conditions of 20°C 68°F at 1 atmospheric pressure 101.3 kPa.
*2 Quality grade of compressed air based on the ISO8573-1Water content values shown in the bracket indicates the dew point temperature at atmospheric pressure.E.g. The “Class 1.2.3” indicates the rating of 0.1 µm 0.004 Mil of the solid particle. –40°C -40°F of dew point under the pressure and 1 mg/m3 oil density.
*3 While the FD-B03 is used, Compound amplitude is 0.45 mm 0.02".
