Why Annual Service Is Critical

In 5–7.5 HP rotary screw compressors, filtration and separation components directly affect airflow quality, oil carryover, and system efficiency.

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

• Extend compressor lifespan

Even smaller horsepower systems experience wear under continuous-duty operation. Preventative maintenance protects uptime and reduces unexpected repair costs.
