Hoffman High-Pressure Ashless Anti-Wear Hydraulic Oil (AF)
Hoffman High‑Performance High‑Pressure Ashless Antiwear Hydraulic Oil (AF) is formulated with multi‑hydrocracking, isomerization‑refined high‑quality base oils and an ashless additive package, blended using state‑of‑the‑art production technologies. Compared with L‑HM antiwear hydraulic oil (high pressure), this product is particularly well suited for lubricating hydraulic systems containing copper and silver components. It is available in grades 32, 46, 68, and 100, based on kinematic viscosity at 40°C.

Detailed Introduction
Hoffman High‑Performance High‑Pressure Ashless Antiwear Hydraulic Oil (AF) is formulated with multi‑hydrocracking, isomerization‑refined high‑quality base oils and an ashless additive package, and is blended using state‑of‑the‑art production technologies. Compared with L‑HM antiwear hydraulic oil (high pressure), this product is particularly well suited for lubricating hydraulic systems containing copper and silver components. It is available in grades 32, 46, 68, and 100, based on kinematic viscosity at 40°C.
Performance Features
◎ A unique zinc- and silicon-free anti-wear formulation that effectively protects silver‑containing components, extending the service life of pumps equipped with silver or silver‑plated parts.
◎ Outstanding wear resistance, demonstrated through a variety of hydraulic pump tests, effectively extends the service life of pumps and systems.
◎ Excellent thermal stability effectively prevents the formation of high-temperature sludge.
◎ Excellent filtration performance, effectively preventing filter clogging.
◎ Excellent oxidation stability, resulting in a longer oil service life.
◎ Excellent rubber compatibility, effectively protecting sealing materials and preventing leaks.
◎ Excellent hydrolytic stability, providing reliable protection even when the system is slightly contaminated with water.
Technical Specifications
◎ GB 11118.1
◎ AFNORNFE48-603HM
◎ ISO 11158 (L-HM)
◎ US steel 136.127
◎ ISO 6743/4 HM
◎ EB 181222
◎ DIN 51524 P2 HLP
◎ SAE MS 1004
Scope of Application
◎ High-performance ashless (zinc-free, silicon-free) hydraulic oil is suitable for hydraulic systems that demand ashless performance, operate under severe conditions, and require long service life.
◎ Suitable for demanding hydraulic systems in balers, injection molding machines, die‑casting machines, presses, and other industrial and automotive equipment; particularly well‑suited for the hydraulic systems of heavy industries such as steel, ceramics, and papermaking.
◎ Also suitable for other systems requiring high‑performance anti‑wear lubrication (low‑load gears, sliding and rolling bearings, air compressors, servo motors, control systems equipped with fine filters, etc.)
