```html

Castrol Alphasyn EP 150 is a premium synthetic industrial gear oil formulated with polyalphaolefin (PAO) base oils and advanced Extreme Pressure (EP) additives. Designed for heavily loaded industrial gear systems, it provides outstanding protection against wear, scuffing and micropitting while delivering excellent thermal and oxidation stability. Its high viscosity index and low pour point ensure reliable performance across a wide operating temperature range.

Application:

Castrol Alphasyn EP 150 is recommended for all types of enclosed industrial gearboxes operating under heavy loads and shock loading conditions. It is particularly suitable for gears and bearings requiring enhanced EP performance. The product is widely used in mining, quarrying, paper production, marine applications and other industrial environments where long service life and maximum equipment protection are essential. It is also suitable for gear systems requiring high resistance to micropitting.

Advantages and benefits:

• Advanced EP protection: protects gears against wear, scuffing and shock loads.
• Excellent micropitting resistance: extends gearbox life and reduces the risk of premature component failure.
• Outstanding thermal and oxidation stability: enables longer oil drain intervals and reduced maintenance costs.
• Wide operating temperature range: high viscosity index and low pour point ensure reliable lubrication in varying conditions.
• Superior corrosion protection: safeguards gears and bearings against rust and moisture-related damage.
• Seal compatibility: compatible with seals manufactured from NBR, silicone and fluoropolymer materials.
• Reduced maintenance costs: longer oil life and improved equipment reliability help minimize downtime.

Classification according to standards:

• DIN 51517 Part 3 – CLP
• ISO VG – 150
• AGMA – 9005-D94 / 9005-E02
• AIST (US Steel) – 224

Approvals and specifications:
The product meets the requirements and recommendations of numerous industrial gearbox manufacturers, including Flender (Siemens MD), David Brown Type E, Hansen Transmissions, Lohmann & Stolterfoht and other gearbox manufacturers requiring CLP-type gear oils with high micropitting resistance.
