Description
Our Atlas Copco Roto RS Ultra compressor oil, part number 1630204120 / 1630-2041-20, offers extended operating life and is ideal for partial-duty rotary screw compressors, which do not require a full 8,000-hour service-life lubricant. In addition, for applications that experience contaminated air, more frequent fluid changes can provide additional protection for the compressor and eliminate high particulate levels from the system.
This Atlas Copco RS Ultra lubricant is a semi-synthetic alternative to many popular OEM air compressor fluids. As the most common series of compressor oils in the industry, our aftermarket Atlas Copco RS Ultra compressor oil is designed to offer outstanding thermal stability, oxidation resistance, a low pour point, and a high flash point. This top-quality lubricant accomplishes all of this while protecting the air compressor against corrosion, rust, and wear.
Made in the USA by a trusted household name.
Typical Compressor Applications:
• Rotary Screw Compressors – ISO 46
