Castrol Alphasyn EP 150 gear oil is a high-quality synthetic lubricant based on poly-alpha olefin (PAO) fluids and sulphur/phosphorus Extreme Pressure (EP) additive technology providing good thermal stability and high load-carrying capacity.

Castrol Alphasyn EP 150 has been formulated for use in all types of enclosed gears including heavy and shock-loaded gears and bearings where EP properties are required.

The Alphasyn EP range is suitable for use in gearboxes where micro-pitting resistance is required and for a wide range of applications in extreme environments, for example, mining and quarrying, marine applications and paper production.

The use of a PAO base stock provides an inherently high Viscosity Index (VI) and low pour points making these products suitable for use over a wide temperature range.

The Alphasyn EP range is fully compatible with nitrile, silicone and fluoropolymer seal materials.

Castrol Alphasyn EP 150 Oil Advantages:

• Full EP performance gives protection of gears against wear and shock loading, including protection against micro-pitting.
• Good thermal and oxidative stability provides reliable operation and extended operating life when compared to mineral oil-based products.
• High corrosion protection for gears.
• An inherently high Viscosity Index (VI) makes the product suitable for operations over a wide temperature range.
• Rapid air release and good performance in the Flender Foam Test prevents foaming and bearing damage.
• Good water separation and demulsification characteristics mean reduced downtime through prolonged lubricant life and increased equipment reliability.
• PAO-based lubricant provides good compatibility with seals, paints and mineral oil-based lubricants.
