ANDEROL S-46 20 L semi-synthetic compressor oil ISO VG 46

ANDEROL S-46 20 L – semi-synthetic compressor oil ISO VG 46

ANDEROL S-46 is a semi-synthetic ISO VG 46 compressor lubricant designed for industrial oil-flooded rotary screw compressors and centrifugal compressors. It is intended for applications where reliable lubrication, resistance to oxidation and control of deposit formation are important operating requirements.

The formulation uses highly refined Group III hydrocarbon base oils and performance additives. The manufacturer identifies ANDEROL S-46 as a semi-synthetic rotary compressor lubricant. The product is supplied in an original 20-litre LANXESS container.

Applications of ANDEROL S-46

ANDEROL S-46 is intended for industrial compression equipment where the manufacturer specifies an ISO VG 46 lubricant with suitable operating characteristics.

• Oil-flooded rotary screw compressors – lubrication of working components in industrial compressed air systems.
• Centrifugal compressors – applications requiring a lubricant with good resistance to oxidation.
• Manufacturing facilities – operation of industrial air compression equipment.
• Maintenance operations – scheduled oil changes in compatible industrial compressors.

Before use, verify the compressor manufacturer's requirements regarding viscosity, base oil technology and operating conditions.

Key benefits of ANDEROL S-46

Semi-synthetic Group III technology

ANDEROL S-46 belongs to the semi-synthetic ANDEROL S compressor lubricant series. Its highly refined hydrocarbon base oils and performance additives provide the lubricating properties required for the intended industrial applications.

Thermal and oxidative stability

The formulation is designed to resist degradation during compressor operation. Thermal and oxidative stability are important for maintaining lubricant performance and limiting the formation of oxidation products.

Deposit control

The manufacturer highlights the deposit and sludge control properties of the ANDEROL S series. These characteristics can help maintain cleaner lubrication systems and reduce operating problems associated with contamination.

Potential for extended oil drain intervals

According to the manufacturer, lubricants from the ANDEROL S series may allow longer oil drain intervals compared with conventional mineral oils. Actual service life depends on compressor design, load, operating temperature, contamination and maintenance requirements.

ISO VG 46 viscosity grade

ANDEROL S-46 belongs to viscosity grade ISO VG 46. Historical technical documentation for this product gives typical kinematic viscosity values of 49 mm²/s at 40°C and 8.1 mm²/s at 100°C.

When should you choose ANDEROL S-46?

ANDEROL S-46 should be considered when the equipment manufacturer specifies an ISO VG 46 compressor lubricant and a semi-synthetic product is suitable for the application.

For maintenance teams, correct lubricant selection and repeatable servicing are important. Engineers should compare the product data with equipment requirements, while purchasing departments can use the exact ANDEROL S-46 designation to identify the required lubricant.

What should you check before use?

• Viscosity grade: verify that the equipment requires ISO VG 46.
• Compressor type: confirm compatibility with the design and lubrication system.
• Technical requirements: compare the lubricant properties with the equipment manufacturer's documentation.
• Lubricant changeover: verify compatibility with the previously used product and the recommended oil change procedure.
• Drain interval: follow the equipment manufacturer's maintenance instructions and actual operating conditions.

Important: two compressor oils with the same ISO VG 46 viscosity grade are not automatically interchangeable.

Melkib Academy – what is the difference between semi-synthetic and synthetic oil?

The classification of a finished lubricant depends on the base oil technology and the manufacturer's product designation. Group III base oils are produced through advanced hydrocarbon refining processes, including hydrocracking.

For ANDEROL S-46, the manufacturer uses the designation Semi-Synthetic Rotary Compressor Lubricant. Therefore, the correct product description is semi-synthetic compressor oil, rather than fully synthetic oil based solely on its Group III base stock.

Storage

Store ANDEROL S-46 in its original, tightly closed container and protect the lubricant from water, dust and other contamination. Use clean tools and suitable containers when transferring the oil. Follow the current safety data sheet for detailed storage and safe handling requirements.

FAQ – frequently asked questions about ANDEROL S-46

Is ANDEROL S-46 a synthetic oil?

The manufacturer classifies ANDEROL S-46 as a semi-synthetic rotary compressor lubricant, not a fully synthetic product.

What compressors is ANDEROL S-46 intended for?

It is primarily intended for oil-flooded rotary screw compressors and centrifugal compressors. Suitability must be checked against the equipment manufacturer's requirements.

Can ANDEROL S-46 replace any ISO VG 46 compressor oil?

No. Viscosity grade alone is not sufficient. Base oil technology, technical specifications, material compatibility and equipment requirements must also be considered.

Can ANDEROL S-46 be used after mineral oil?

Before changing lubricants, check product compatibility and the recommended oil change procedure. Similar material compatibility to mineral oils does not mean that unrestricted mixing is permitted.

Are ANDEROL S-46 and S-46-A the same product?

They should not be considered fully equivalent without confirmation from the manufacturer. This product card refers specifically to ANDEROL S-46 as identified on the original packaging.

How often should ANDEROL S-46 be changed?

The oil drain interval depends on compressor design and operating conditions. Follow the equipment manufacturer's instructions and consider oil condition monitoring results.

What does ISO VG 46 mean?

ISO VG 46 is a kinematic viscosity grade defined at 40°C. Historical ANDEROL S-46 documentation gives a typical viscosity of 49 mm²/s at this temperature.

Is ANDEROL S-46 suitable for every rotary screw compressor?

No. Check the required viscosity grade, lubricant type, operating conditions and equipment manufacturer's recommendations before use.
