About the product
Technical details and applications
CompStar S is a synthetic air compressor lubricant, formulated with PAO synthetic oils and performance-enhancing additives.
It is recommended for lubricating rotary screw compressors operating at temperatures of up to 120°C, with drain intervals of 8,000 hours of use: twice the interval of the semi-synthetic and far above the mineral option.
The PAO base provides oxidation resistance through excellent thermal stability, anti-wear and anti-corrosion protection, excellent demulsibility (water separation) and compatibility with mineral lubricants. The product is available in ISO VG 46 viscosity.
Applications
- Rotary screw compressors
- Continuous operation up to 120°C
- Applications requiring a long drain interval (8,000 h)
Advantages
- 8,000-hour drain interval: PAO doubles oil life compared with the semi-synthetic.
- Handles 120°C: thermal stability sustains hot screw operation.
- Separates water: excellent demulsibility protects the compressor.
- Compatible with mineral oil: makes migrating from the previous oil easier.
