Why the 500 Hour Service Matters

Rotary screw compressors rely on clean, properly filtered oil for lubrication, cooling, and sealing. During operation, contaminants accumulate in the lubricant and filtration system.

Replacing the oil filter and analyzing lubricant condition at 500 hours helps:

  • Maintain proper oil flow

  • Protect the airend from contamination

  • Prevent bearing and rotor damage

  • Preserve energy efficiency

  • Detect early signs of internal wear

  • Extend compressor lifespan

Skipping early service is one of the fastest ways to reduce compressor reliability.

OEM Quality for NX Series Protection

Using OEM components ensures:

  • Proper filtration performance
