Acceptable baseline conditions are a non-cycling (e.g. continuous) air dryer with a capacity of 600 cfm or below. The replacement of desiccant, deliquescent, heat-of-compression, membrane, or other types of dryers does not qualify under this measure. Efficient conditions are a cycling thermal mass dryer with a capacity of 600 cfm or below.
