The indicated oil exchange intervals are valid for standard operating conditions (see section Reference
conditions and limitations) and nominal operating pressure (see section Compressor data). Exposure of the
compressor to external pollutants, operation at high humidity combined with low duty cycles or operation
at higher temperatures may require a shorter oil exchange interval. Contact Atlas Copco if in doubt.
