Product Description
FUCHS RENOLIN ZAF 22 is a premium ISO VG 22 zinc-free and ash-free anti-wear hydraulic oil designed for industrial hydraulic systems, CNC machine tools, precision hydraulic equipment, injection moulding machines, hydraulic presses, manufacturing machinery, circulating lubrication systems, and mobile hydraulic equipment. This high-performance HLP hydraulic fluid delivers outstanding wear protection, oxidation stability, corrosion resistance, rapid air release, excellent water separation, and long service life while preventing zinc contamination in sensitive manufacturing applications. It is particularly recommended for machine tools where hydraulic oil may come into contact with metalworking fluids.
RENOLIN ZAF 22 is formulated with premium mineral base oils and advanced zinc-free, ash-free anti-wear additive technology to provide exceptional protection for hydraulic pumps, servo valves, bearings, and precision hydraulic components. The formulation offers excellent ageing resistance, demulsibility, filterability, and seal compatibility, helping maximise equipment reliability while reducing maintenance costs and extending oil service intervals.
