3. Performance Features & Benefits
- Excellent oxidation stability — resists oil degradation and varnish formation at elevated compressor temperatures
- Very low carbon residue (Conradson ≤ 0.05%) — minimises carbon deposit build-up on valves and discharge lines
- Effective anti-wear protection — extends compressor component life under high-pressure conditions
- Outstanding rust and corrosion protection for ferrous and non-ferrous metals
- Good water separation — prevents emulsification from condensate contamination
- Low foam tendency and rapid air release — maintains consistent oil film and system pressure
- Compatible with standard compressor seals (NBR, FKM)
- Extended drain intervals vs. standard turbine oils — reduces maintenance frequency
4. Applications
- Rotary screw air compressors (oil-flooded)
- Reciprocating (piston) air compressors — cylinder and crankcase lubrication
- Rotary vane air compressors
- Industrial vacuum pumps (oil-sealed rotary vane and piston types)
- Air tools and pneumatic equipment requiring compressor oil lubrication
- General-purpose circulating oil systems in compressor stations
