ENVIRON™ AW 46 – ashless, zinc‑free hydraulic oil for environmentally sensitive areas

ENVIRON™ AW 46 is a premium ashless and zinc‑free hydraulic fluid designed for mobile and stationary high‑performance hydraulic systems. It is inherently biodegradable and ideal for use in environmentally sensitive applications.

Formulated with ultra‑pure base oils and a modern metal‑free additive system, ENVIRON AW 46 provides excellent wear protection, outstanding oxidation stability, superior water separation and excellent hydrolytic stability.

Product Advantages
• Ashless and zinc‑free – no metal contamination
• Inherently biodegradable (>30 % OECD 301B)
• Non‑toxic to fish, daphnia and algae
• Excellent oxidation and thermal stability
• Outstanding wear, rust and corrosion protection
• Excellent demulsibility and air release
• Very good foam resistance
• Fully recyclable (not plant‑oil based)

Typical Applications
• Hydraulic systems in environmentally sensitive areas
• Mobile equipment (construction, forestry, municipal)
• Industrial hydraulic systems
• Injection molding machines
• Systems with silver bearings (zinc‑free)
