Note 2) This describes the grade of compressed air quality based on ISO8573-1: 2001 (JIS B8392-1: 2003), which is the maximum quality grade for the system. It varies, however, depending on the inlet air conditions.

Not required when attached to air compressors. Air tank is not required for rotary screw compressors since pulsation is small, but required when it is used to accumulate pressure. Required for reciprocating air compressors since carbon and tarry substances are generated at high temperatures. 5
