Product Description

This product is formulated using high-quality synthetic oil as the base, combined with a blend of advanced additives—including antioxidants, rust inhibitors, corrosion protectants, and anti-foaming agents—through a state-of-the-art manufacturing process.

Product Performance

Excellent thermal stability and oxidation stability effectively prevent the formation of oxide sludge, varnish films, and carbon deposits.

Excellent wear resistance, high oil film strength, effectively preventing and reducing component wear;

Excellent rust and corrosion resistance provide superior protection for the compressor;

Excellent 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

Instructions for Use and Precautions

Select the appropriate oil 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.
