Description
Castrol Hyspin ZZ 22 Superclean
Product Description
Castrol Hyspin ZZ 22 Superclean is a high-performance low-viscosity, zinc-free (ashless) anti-wear hydraulic oil designed for precision hydraulic systems operating under light loads and low temperature conditions. It provides excellent wear protection, fast air release, and outstanding filterability for highly sensitive hydraulic circuits.
Its “Superclean” filtration standard ensures a very high level of cleanliness, making it ideal for servo-controlled systems and precision equipment where contamination control is critical.
