Description
Sinopec L-DAG Low Duty Oil Injection Rotary Compressor Oil is a lubricating oil blended with highly refined mineral base oil and well-chosen additives for anti-oxidation and anticorrosion. It is suitable for lubrication of various low duty oil injection rotary air compressors. The product comprises several grades such as 32, 46, and 68 according to its kinematic viscosity at 40℃.
Applications:
Sinopec L-DAG Low Duty Oil Injection Rotary Compressor Oil is suitable for use in:
- Lubrication of rotary air compressors in conditions of discharge temperature less than 100℃ and valid work pressure less than 800 kPa.
Features and Benefits:
- Relatively low ash content: Reduces carbon deposit, avoiding formation of flash explosions.
- Good anti-oxidation performance: Capable of bearing circulation applications vulnerable to oxidation, with a relatively long oil drain interval.
- Good anti-rust performance.
Good oil-water separation performance.
