It is thin enough to flow easily through the narrow passages of the compressor and expansion valve, yet thick enough to maintain a protective barrier on moving metal parts. Once opened, the container should be used promptly and sealed tightly immediately after.
Understanding Pag 46 Oil: Viscosity, Performance, and Handling for AC Compressors
Viscosity and Performance The number "46" in Pag 46 refers to the oil's kinematic viscosity at 100°C, measured in centistokes (cSt). Understanding Polyalkylene Glycol (Pag) Oil Pag, which stands for Polyalkylene Glycol, is a synthetic ester-based lubricant engineered to meet the demanding requirements of refrigeration systems.
Identifying the Need for Replacement While Pag 46 oil is durable, it does not last indefinitely. This characteristic means that handling requires precision and care.
Understanding Pag 46 Oil for AC Compressor Performance
This specific viscosity grade strikes a balance between fluidity and film strength. Furthermore, the system must be evacuated (pulled to a vacuum) for an adequate period during installation to remove any ambient moisture that the oil may have absorbed, as moisture in the system leads to acid formation and ice blockages, which can severely damage the compressor.
