Answer: Air compressor oil can be divided into two categories according to the type of base oil: mineral oil air compressor oil and synthetic air compressor oil.
According to the structural type of the air compressor, air compressor oil is divided into two types: reciprocating air compressor oil and rotary air compressor oil. Each type has three levels: light, medium and heavy load. At present, the domestically standardized reciprocating air compressor oil varieties are L-DAA and L-DAB. The specification standard is GB 12691-1990 "Air Compressor Oil", and the viscosity grades are divided into five grades: 32, 46, 68, 100, and 150.
The rotary air compressor oil varieties include for light load, for medium load, and for heavy load. The viscosity grades are 15, 22, 32, 46, 68, and 100. Among them, DAG is a mineral oil type, DAJ is a synthetic type, and DAH oil is a new type of high-quality screw air compressor oil prepared from hydrogenated base oil. It has excellent thermal oxidation stability and low carbon deposition tendency.
