Note 1) When the inlet oil mist density (compressed air density) is approximately 30 mg/m3 (ANR) or less.
Note 2) This describes the grade of compressed air quality based on ISO8573-1: 2010 (JIS B8392-1: 2012), which is the maximum quality grade for the system. It varies, however, depending on the inlet air conditions.
