Vetus WOA004Z Weld-On Zinc Hull Anode Rectangular 3.00 kg
The Vetus WOA004Z is a rectangular weld-on zinc hull anode engineered for reliable cathodic protection of underwater metal components on vessels operating in saltwater and brackish environments. Zinc anodes are recommended for these conditions due to their stable electrochemical behavior and controlled consumption rate. This anode is manufactured from high-purity zinc in accordance with MIL-A-18001K specifications, ensuring consistent and dependable corrosion protection.
For vessels operating mainly in inland (fresh) waters, aluminium anodes are recommended, as aluminium offers a greater potential difference under high electrical resistance conditions. In saltwater and brackish water, zinc remains the optimal solution. The WOA004Z is supplied with galvanized steel tags, allowing direct weld-on installation to metal hulls for a low-profile and permanent mounting solution. Its increased mass makes it suitable for primary protection zones on medium and large hulls.
Key Features
- Weld-on zinc hull anode for saltwater and brackish water
- Manufactured to MIL-A-18001K specification
- Rectangular streamlined contour
- Galvanized steel tags for easy welding
- High capacity for extended service life
