Description

Solar Hydraulic Oil ISO AW 37 is a high-performance anti-wear hydraulic fluid formulated from premium quality mineral base oils combined with a balanced additive package to deliver excellent protection and performance. It is designed for hydraulic systems requiring a slightly higher viscosity than ISO VG 32 but lighter than ISO VG 46, making it ideal for moderate climate conditions and precise hydraulic operations.

Available API

ISO

Applications

Industrial hydraulic systems operating in light to moderate conditions.
Mobile construction and agricultural equipment.
Hydraulic presses, injection molding machines, and CNC systems.
Systems requiring ISO VG 37 oils with anti-wear and rust preventive properties.
Recommended for use in climates where ISO 32 may be too light and ISO 46 too heavy.

Features & Benefits

Outstanding Anti-Wear Protection– Helps extend the life of hydraulic pumps and components.
Superior Oxidation Stability– Reduces varnish and sludge formation, leading to longer service life.
Excellent Rust and Corrosion Prevention– Guards critical system parts, especially in humid environments.
Fast Air Release and Low Foaming– Ensures smooth and consistent hydraulic operation.
Good Demulsibility– Quickly separates water to prevent emulsification and maintain efficiency.
Stable Viscosity– Provides reliable lubrication under varying temperatures.

Health & Safety:

Avoid prolonged contact with skin. Wear protective gloves and clothing when handling.
In case of skin contact, wash with soap and water. Seek medical advice if irritation persists.
Do not ingest. If swallowed, seek immediate medical assistance.
Avoid breathing oil mist. Use in well-ventilated areas.
