Change the separator at the hours in the compressor's service plan, usually together with the oil and the oil filter, and sooner if oil carry over or the separator pressure drop rises.

Breakdown spares
Keep one on the shelf so a loaded air/oil separator element does not stop the machine while parts are ordered.

Workshop and fleet stock
Workshops looking after several machines can stock this one element under any of its 27 part numbers.
