Start with the application
Selecting a lubricant starts with equipment requirements and the product's intended application. The published Compressor VDL 46 product page describes a series for lubricating compressors made in Russia and abroad. A product's presence in the industrial category does not by itself confirm suitability for every industrial component.
Check the viscosity grade
The Compressor VDL 46 product page specifies ISO VG 46 and gives a range for kinematic viscosity at 40 °C. Check the full product name and its corresponding properties table. A different viscosity number in the name identifies a different catalogue product.
Read the specifications
The online shop lists DIN 51506, Part 3 (VDL) for this product. Compare the specification on the product page with the compressor manufacturer’s requirements. A shared word in a product name is not a basis for claiming complete interchangeability with any other material.
Open the document
The product page provides a technical data sheet for the Compressor VDL range. Check the range name and applicable viscosity in the document. If a quality certificate for a specific batch or another supporting document is needed, request it from the supplier or manufacturer.
Describe your technical enquiry
If the equipment requirements and product description do not allow an unambiguous choice, provide the compressor model, operating conditions, required specifications and the material currently in use. This gives the specialist the information needed for a practical discussion.
