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.

Annual service helps:

• Maintain optimal CFM output

• Reduce pressure drop across filtration components

• Protect the airend from contamination

• Minimize oil carryover

• Preserve energy efficiency

• Detect lubricant degradation through oil sampling

• Prevent costly downtime

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