  Deep refined base oil is used, ashless anti-wear hydraulic oil additive is added, and it is scientifically formulated and blended into a new blending process.

This product does not contain ash and other ash components. It provides special protection for high-grade hydraulic systems including silver and copper. It has superior anti-wear, anti-rust, anti-corrosion, anti-foam and demulsification properties.
With excellent low temperature performance, it can start smoothly in cold conditions.
Good anti-emulsification, can quickly separate from the contacted moisture. Good rubber seal adaptability ensures good sealing.
For factories and mines require the use of ash-free anti-wear hydraulic oil system and conventional anti-wear hydraulic system.
