Compressor oil is suitable for medium- and heavy-duty reciprocating air compressors, as well as for light- and medium-duty rotary air compressors with drip lubrication. The dataset includes major raw and auxiliary materials, energy inputs, and waste generated during the production process, but excludes infrastructure such as production equipment and factory buildings from the system boundary. The life cycle inventory is compiled from data collected from multiple sources. The manufacturing process of compressor oil comprises raw material preparation, heating, additive dosing, full analysis, packaging, and other related steps.
