Why Quarterly Maintenance Is Critical

25–30 HP rotary screw compressors are often production workhorses. Over time, dust, airborne contaminants, and oil degradation can impact performance and efficiency.

Replacing filters and performing oil analysis every quarter helps:

• Maintain proper airflow and CFM output

• Prevent pressure drop caused by restricted filtration

• Protect the airend from contamination

• Preserve energy efficiency

• Detect early signs of lubricant breakdown

• Extend overall compressor life

Preventative maintenance is far less expensive than production downtime.

OEM Quality for NX Series Protection

This is a genuine FS-Curtis service kit, engineered specifically for NX Series compressors.

Using OEM components ensures:

• Proper micron filtration

• Correct fit and sealing

• Maintained warranty compliance

For facilities enrolled in the NXGEN Extended Warranty Program, following the required maintenance schedule with genuine parts is essential to preserve coverage.
