Why Annual Service Is Critical
In 40–50 HP rotary screw systems, the air/oil separator and filters play a major role in maintaining efficiency and protecting internal components.

-
Protect the airend from contamination

Neglecting separator replacement can increase energy consumption and strain internal components.
