Ideal for applications like mining, forestry, marine, and construction, Lubrizol AH933ZF delivers proven performance against an extensive list of OEM performance specifications and provides differentiated hydraulic performance that can make a difference for lubricant manufacturers, equipment OEMs, and end users alike.
Lubrizol has launched AH933ZF, a zinc-free additive package for hydraulic fluids offering robust performance for mining, forestry, marine and construction sectors.
It enhances anti-wear protection, oxidation stability, foam control and formulation flexibility.
With zinc-free fluids set to grow 4.25 per cent CAGR (2024–2029), the innovation meets rising demand for cleaner, efficient solutions.
Lubrizol AH933ZF benefits include:
- Reduced downtime and extended equipment life. With anti-wear chemistry for durable protection, fluid formulators can deliver reduced downtime and total cost of ownership for critical machinery.
- Extended drain intervals. With advanced oxidation protection and thermal stability, Lubrizol AH933ZF can extend service intervals for more efficient operation.
- Precise operation and increased productivity. Lubrizol AH933ZF delivers air release and foam control, contributing to smooth and efficient hydraulic control.
- Formulation flexibility. Lubrizol AH933ZF maintains a wide base oil read-across window, allowing formulators to deliver high-performance finished fluids with many Group II base oils, enabling fast, low-cost development and enhanced speed to market.
Lubrizol AH933ZF arrives as demand for zinc-free solutions continues to rise. Zinc-free hydraulic fluids in North America and Europe are projected to experience a compound annual growth rate (CAGR) of 4.25% from 2024-2029, whereas demand for traditional zinc-based fluids is expected to decrease over that same time, at -0.43% CAGR, according to research from Kline & Company.
“In a world demanding cleaner solutions with enhanced performance, Lubrizol continues to lead the way,” said Jared Cornett, Product Manager, Industrial Oils, Lubrizol. “Lubrizol AH933ZF is a demonstration that high-performance, zinc-free hydraulic fluids are not only possible, but that they can outperform conventional formulations with the right science.”
