Everything required for a complete quarterly service in one package.

Why Quarterly Service Is Critical

40–50 HP rotary screw compressors are typically production workhorses. Dust, oil degradation, and airborne contaminants can quickly reduce efficiency if maintenance is delayed.

Replacing filters and performing oil analysis every quarter helps:

• Maintain proper airflow and CFM output

• Protect the airend from contamination

• Prevent pressure drop from restricted filtration

• Monitor lubricant condition through oil sampling

• Maintain energy efficiency

• Extend compressor life

In high-duty industrial environments, preventative maintenance costs far less than unscheduled downtime.

Protect Your NX Investment

The NX Series is engineered for reliability, but only when maintained properly. Using OEM FS-Curtis filters ensures:

• Correct micron filtration

• Proper fit and sealing

• Maintained warranty compliance

• Maximum system efficiency

If your facility participates in extended warranty programs, using genuine service kits is essential.
