Performing service at the 500-hour mark is critical to protecting your airend, maintaining efficiency, and preventing premature wear in continuous-duty rotary screw compressors.
Each kit contains genuine FS-Curtis components:

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.
