Why Annual Service Is Critical

In 25–30 HP rotary screw compressors, filtration and separation components directly impact efficiency and performance.

Replacing these components annually helps:

• Maintain rated CFM output

• Reduce pressure drop across filters

• Minimize oil carryover

• Protect the airend from contamination

• Improve overall energy efficiency

• Detect lubricant degradation early through oil analysis

• Prevent costly downtime

A restricted separator alone can significantly increase energy consumption and strain internal components.
