Synthetic PAG/Ester Base Compressor Oils combine the dynamic metal-preserving properties of synthetic polyalkylene glycol (PAG) and ester bases. These synthetic fluids blend thoroughly and provide the extreme pressure performance of PAG (without the EP additives)* and the heat and cold-resistant properties of ester-based fluids.
ISO VG 46 oil has a midpoint kinematic viscosity of 46 mm2/s, also referred to as centistokes (cSt). The midpoint is derived by taking the average of both the minimum and maximum kinematic viscosities. In the case of ISO VG 46 oil, those numbers are 50.6 cSt and 41.4 cSt, respectively. These numbers refer to the standard testing mechanisms used to determine how much resistance to flow (i.e. viscosity) these oils demonstrate.
