Premium performance synthetic compressor fluids
Cetus PAO are a range of premium performance synthetic compressor fluids, designed to meet the requirements of modern higher output, more efficient air compressors, where speeds and temperatures are higher, increasing deposit formation. Cetus PAO are recommended for use in rotary screw compressors, single and multistage reciprocating units, and single and multistage centrifugal compressors.
Cetus PAO fluids are formulated with an advanced combination of polyalphaolefins with advanced additive technology, offering good hydrolytic stability, high viscosity index, improved thermal and mechanical efficiency, lower coefficients of friction, high thermal stability, and excellent heat-transfer properties.
Benefits
- Promotes high temperature performance and protection through robust oxidation stability
- Premium wear protection performance helps contribute to increased productivity and reduced equipment downtime
- Low pour point offers good protection in low temperature climates
- Good air release properties aid performance in oil flooded screw compressor applications
- Seal swell agents help protect against oil leaks
- Extended drain potential assists in downtime reduction
Applications
- Cetus PAO oils are formulated to provide excellent lubricating qualities for many air compressors, especially portable and stationary rotary, and screw compressors as well as single-stage, two-stage, and multistage reciprocating compressors. By using a synthetic compressor oil, efficiency improvements up to 5% in comparison with mineral oilbased products can be expected. While specific OEM recommendations vary, the ISO 46 and 68 grades are most used for rotary air compressors. While higher viscosity grades are preferred for reciprocating air compressors. Since reciprocating compressors require both a crankcase lubricant and a cylinder lubricant, Cetus PAO oils are formulated to meet this dual requirement. Cetus PAO 68 is specially developed for the lubrication of turbochargers in marine diesel engines, where two separate lubricating oil systems are in place. Cetus PAO 46 is used in Knorr-Bremse sliding vane compressors. Cetus PAO 68 is used in Knorr-Bremse rotating vane compressors. Cetus PAO 68 is suitable for the lubrication of turbochargers in marine diesel engines. Cetus PAO 68 can be used for vacuum pumps GPM 65 ATEX II 2G IIB 4, from Axlow LTD
