This product is formulated using a deeply refined, high-viscosity base oil combined with advanced additives that provide antioxidant, anti-rust, anti-corrosion, and anti-foam properties—all blended together through state-of-the-art manufacturing processes.

Product Performance

Good oxidative stability effectively reduces carbon deposit formation and inhibits oil degradation, extending the service life of the lubricant.

Excellent rust and corrosion resistance, preventing cylinder and exhaust valve corrosion;

Good anti-foaming and water-separating properties effectively prevent emulsion-induced oil film breakdown and reduce increased wear.

Technical Specifications

GB/T 12691-2021

Scope of Application

Suitable for lubrication, cooling, and sealing applications in various medium- and high-pressure reciprocating air compressors and crankcases.

Instructions for Use and Precautions

Select oil products with the appropriate viscosity according to the equipment's lubrication guidelines. During use and storage, prevent contamination by foreign objects, and strictly avoid mixing in mechanical impurities or water. Ensure the oil tank remains clean—when changing the oil, thoroughly flush both the tank and oil lines. Never mix this oil with other types, and never combine different categories of oils.
