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. Pag 46 oil serves three primary functions within this environment: lubrication, cooling, and sealing.
Pag 46 Oil for R134a Systems: Best Practices for Installation and Handling
Contaminants from wear particles, metal dust, and acid buildup can degrade its effectiveness over time. Once opened, the container should be used promptly and sealed tightly immediately after.
This characteristic is essential for reducing friction, minimizing wear, and preventing the noise and damage associated with metal-on-metal contact. Unlike traditional mineral oils, Pag oil exhibits superior solubility with the refrigerants used in today’s vehicles, such as R134a and R1234yf.
Pag 46 Oil for R134a Systems Best Practice: Key Installation and Handling Tips
Installation and Handling Best Practices Due to its highly hygroscopic nature, Pag 46 oil absorbs moisture from the air very readily. It reduces friction between the internal vanes or rotors, carries away heat generated by compression, and helps maintain the tight clearances necessary to prevent refrigerant leakage, thereby maximizing the system's efficiency.
