Description
Product Description
FUCHS RENOLIN ZAF 5 is a premium zinc-free and ash-free hydraulic oil (HLP hydraulic fluid) specially developed for precision hydraulic systems, machine tools, circulating lubrication systems, spindle applications, and equipment where contamination with metalworking fluids may occur. Formulated with high-quality base oils and advanced zinc-free additive technology, it provides excellent ageing resistance, superior corrosion protection, reliable wear protection, excellent filterability, good water separation characteristics, and long service life.
The zinc-free formulation makes RENOLIN ZAF 5 particularly suitable for applications where conventional zinc-containing hydraulic oils may cause issues, especially in machine tools and metal processing industries where hydraulic oil and cutting fluids can come into contact.
