Air conditioning compressor oils: differences, selection and use

types of car climate oils 1. pag oils (polyalkylene glycol) The most common type of car air conditioning oil for R134a and R1234yf refrigerants. Why is pag oil used? mixes very well with refrigerant ensures smooth operation of the compressor suitable for most modern vehicles The main viscosity classes of pag oils: page 46 – for smaller compressors, new cars pag 100 – for standard compressors pag 150 – for larger systems (trucks, buses) pros: optimal compatibility with R134a and R1234yf systems good lubricity disadvantages: hygroscopic (draws moisture from the air) 2. store oils (polyol ester) The store's oils are also synthetic and are particularly suitable for electric compressors and hybrid cars , where electrical insulation is required. What is store oil used for? in r134a and r1234yf systems in vehicles where the compressor is electrically controlled in compressors that require special dielectric oil Common store viscosity grades: shop 32 shop 46 shop 68 shop 100 3. PAO oils (polyalphaolefin) – versatile and moisture resistant PAO oils are synthetic oils that are non -hygroscopic, meaning they do not absorb moisture. This makes them useful in difficult conditions. Why choose pao oil? suitable for both r134a and r1234yf refrigerants can be used when unsure of what pag viscosity is needed better moisture resistance Common escape classes: escape 68 escape universal Universal PAO is popular in repair shops because it is suitable for many systems and is stable. 4. mineral oils (mo / mineral oil) mainly used in older systems with R12 refrigerant . Where are mineral oils used? classic cars old air conditioning systems that operate with R12 or its substitutes ... More...
