In real-world use

A worn separator lets oil carry over into the air line, which shows up as oil in the receiver drain and rising oil consumption. A blocked one raises the pressure drop and costs power on every hour of running. Change it on the compressor's service interval or when the separator differential pressure reaches the limit in the manual.
