Alphasyn HG synthetic fluids are synthetic high-performance lubricants which are polyalphaolefin-based. Formulated with specially selected additives Alphasyn HG offers a versatile range of fluids suitable for use in both gear and bearing applications.

The range has been designed to offer specific performance benefits over its conventional mineral oil and synthetic fluid counterparts.

Castrol Alphasyn HG 150 is particularly suitable for applications at high operating temperatures and loadings, Alphasyn HG provides superior performance benefits including excellent thermal and oxidation stability and enhanced load-carrying ability as detailed below

Castrol Alphasyn HG 150 offers a wide range of performance benefits over a conventional lubricant when used in gear and bearing applications:

• Substantially extended lubricant life.
• Excellent anti-wear, extreme pressure and load-carrying properties lead to savings in both maintenance time and costs.
• Exceptional lubricity properties increase mechanical efficiency and minimise energy losses. proven superior performance across a wide temperature range and in particular at high temperatures.
• Excellent thermal and oxidative stability.
• Advanced lubricant properties such as viscosity characteristics, low pour point and good air and water separation capabilities.

Fully compatible with standard seal, paint and hose material, and with Ortlinghaus multi-plate clutches.
Castrol Alphasyn HG 150 synthetic fluid passes the standard FZG test (A/8.3/90) with a fail load stage greater than 12 and also the more severe FZG test (A/16.6/140) at fail load stage 10.
Alphasyn HG range meets the IP 135B corrosion and ASTM D2893 oxidation tests.
Castrol Alphasyn HG 150 meets the following;

• DIN 51517 pt 3, Industrial gear oil specification.
• DIN 51524 pt 2, Industrial hydraulic oil specification.

Care and Handling
Avoid prolonged or repeated contact with skin. Wash thoroughly after handling.

Storage
All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and the obliteration of drum markings. Products should not be stored above 60C, or exposed to hot sun or freezing conditions.
