Description
Sinopec L-DAH Oil Injection Rotary Air Compressor Oil is blended with hydrogenated base oil and multi-functional additives. It is suitable for lubrication of various kinds of moderate duty oil injection rotary (screw and sliding-vane) air compressors. The product comprises several grades such as ISO 32, 37, 46, and 68 according to its kinematic viscosity at 40℃.
Applications:
Sinopec L-DAH Oil Injection Rotary Air Compressor Oil is suitable for use in:
- Lubrication of rotary air compressor (screw and sliding-vane) with discharge temperature less than 100℃ and valid work pressure of 800 kPa to 1500 kPa, or discharge temperature of 100℃ to 110℃ and valid work pressure of 800 kPa.
Features and Benefits:
- Outstanding anti-oxidation stability: Ensures very long service life.
- Excellent oil-water separation performance.
- Excellent anti-wear performance.
- Good anti-rust performance.
