Overview
COMPRESSOR TECH Polyalphaolefin- Synthetic (PAO-S) is a synthetic industrial compressor oil formulated on polyalphaolefin (PAO) base stock. It is offered in ISO VG 32, ISO VG 46, ISO VG 68, ISO VG 100.
The specification table lists, for each grade, kinematic viscosity at 40 °C and 100 °C, viscosity index, pour point, flash point and acid number, each with its test method. Share operating conditions with our technical team to confirm the grade before supply.
Application
Compressors whose manufacturer calls for a PAO-based oil.
Feature
ISO VG 32: KV40 34 cSt, KV100 5.8 cSt, VI 134, pour point -45 °C; ISO VG 46: KV40 46 cSt, KV100 6.2 cSt, VI 143, pour point -45 °C; ISO VG 68: KV40 69 cSt, KV100 8.1 cSt, VI 148, pour point -48 °C; ISO VG 100: KV40 95 cSt, KV100 10.7 cSt, VI 154, pour point -51 °C.
Feature
Published kinematic viscosity at 40 °C sits inside the ISO 3448 tolerance (mid-point ±10 %) for ISO VG 32 (34 cSt); ISO VG 46 (46 cSt); ISO VG 68 (69 cSt); ISO VG 100 (95 cSt).
Feature
Besides viscosity, the published data includes acid number, flash point (COC) and foaming tendency.
Start from the equipment manufacturer's viscosity recommendation at operating temperature. The ISO VG number is the mid-point kinematic viscosity at 40 °C (ISO 3448), and each grade's published values are listed separately.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
