-
• Excellent Anti-Wear ProtectionWhat Is Ash-Free Hydraulic Oil?
Ash-free hydraulic oil, also known as zinc-free hydraulic oil, is formulated without metal-containing anti-wear additives.
Instead, it uses advanced non-metallic additive technology to provide excellent anti-wear performance while minimizing ash deposits.
Key advantages include:
Cleaner hydraulic system operation
Reduced valve sticking
Lower deposit formation
Improved filterability
Better long-term oxidation stability
This makes ash-free anti-wear hydraulic oil ideal for modern precision hydraulic systems.
Why Choose Zinc-Free Anti-Wear Hydraulic Oil?
Compared with traditional zinc-based hydraulic oil, zinc-free hydraulic oil offers several important benefits:
Extended Oil Service Life
Superior oxidation stability and thermal resistance help extend oil change intervals, reduce maintenance frequency, and minimize equipment downtime.
Excellent Anti-Wear Protection
Advanced zinc-free additives provide strong wear protection under both light and heavy loads.

Frequently Asked Questions (FAQ)
What is ash-free hydraulic oil?
Ash-free hydraulic oil is a zinc-free hydraulic fluid designed to reduce ash deposits, improve system cleanliness, and provide effective anti-wear protection in industrial hydraulic systems.
What is the difference between zinc-free and zinc-based hydraulic oil?
Zinc-free hydraulic oil uses non-metal additives, which help reduce deposit formation and improve compatibility with sensitive hydraulic components, while zinc-based oils use metal additives for wear protection.
Which hydraulic oil viscosity should I choose: 32, 46, or 68?
ISO VG 32 is recommended for cold environments and high-speed systems, ISO VG 46 is suitable for standard industrial applications, and ISO VG 68 is ideal for high-load and high-temperature conditions.
