Why Quarterly Maintenance Matters

In 5–20 HP rotary screw compressors, airborne contaminants and oil degradation can quickly impact performance.

Replacing the air filter, oil filter, and analyzing lubricant condition every quarter helps:

• Maintain proper airflow and rated CFM

• Prevent pressure drop from restricted filtration

• Protect the airend from contamination

• Preserve energy efficiency

• Detect lubricant breakdown early

• Extend overall compressor life

Routine maintenance dramatically reduces the risk of unexpected downtime.
