Ashless Anti-Wear Formula DIN 51524 HL/HLP/HVLP

S.O. HYDROIL AF

S.O. HYDROIL AF is a premium ashless anti-wear hydraulic oil specially engineered for industrial power transmission systems requiring low-ash or zinc-free lubricant chemistry.

Formulated with advanced ashless additive technology, this oil delivers outstanding oxidation stability, thermal resistance, anti-wear protection, and anti-corrosion control. It minimizes sludge deposit formation, is compatible with silver metallurgy, and exceeds stringent international standards including DIN 51524 Part 1, 2, 3 (HL, HLP, HVLP), AFNOR NFE 48-603, ISO 13357-2 (Wet & Dry filterability), ISO 11158, and Eaton Vickers I-286-S.

Technical Datasheet Technical Data Sheet (PDF)

Minimizes Sludge Deposits

Ashless chemistry prevents thermal sludge and varnish buildup, ensuring ultra-clean system operation and valve responsiveness.

Superior Thermal & Oxidation Stability

High thermal resistance prevents fluid degradation under continuous high-temperature power transmission demands.

Excellent Anti-Wear & Rust Protection

Advanced anti-wear additive package protects precision pumps, pistons, and actuators while safeguarding metal surfaces from rust.

Compatible with Silver Materials

Zinc-free formulation is safe for hydraulic pumps and control systems containing delicate silver-plated parts.

Demulsibility & Anti-Foam Properties

Rapidly sheds water contamination and suppresses entrained air bubbles to maintain consistent hydraulic response.

Superior Filterability (ISO 13357-2)

Passes ISO 13357-2 Wet & Dry filterability testing, ensuring smooth flow through ultrafine filtration systems without clogging.
