Vetus AIRVENTV Anti-Syphon Airvent with Valve for Ø13–32 mm Marine Hoses
The Vetus AIRVENTV anti-syphon airvent is designed to prevent vacuum formation in marine engine cooling systems by using a self-regulating pressure valve that activates only when necessary. Suitable for hoses with internal diameters of Ø13 mm, Ø19 mm, Ø25 mm, and Ø32 mm, it provides essential protection for engines whose cooling water injection point lies less than 15 cm above the waterline. Constructed from durable synthetic materials and stainless steel components, this unit ensures long-term reliability in harsh marine environments.
Main Features
- Compatible with Ø13, Ø19, Ø25, and Ø32 mm internal hose diameters.
- Self-regulating siphon valve vents only when required.
- Prevents vacuum formation in the cooling water circuit, protecting the engine.
- Suitable for installations where exhaust water injection is close to the waterline.
- Constructed from corrosion-resistant synthetic materials with stainless steel valve parts.
- Requires periodic maintenance to prevent salt crystal buildup.
- Mounting brackets available for installations on insulated surfaces.
Applications
- Marine Engines: Prevents siphoning of cooling water into the exhaust and engine after shutdown.
- Water-Injected Exhaust Systems: Maintains pressure balance when the injection point is low.
- General Cooling Circuits: Ensures proper ventilation and prevents backflow due to vacuum.
Technical Specifications
Function Anti-syphon airvent with pressure valve Hose Compatibility Ø13 / Ø19 / Ø25 / Ø32 mm Length 98 mm Width 50 mm Height 162 mm Valve Type Self-regulating pressure valve Materials Synthetic housing; synthetic and stainless-steel valve components
Installation Notes
- Install at least 40 cm above the waterline for optimal anti-syphon protection.
- Position the unit at a point where vacuum risk is highest in the cooling system.
- Perform routine checks to ensure the valve remains free of salt deposits.
- Mounting brackets (optional) allow for installation on sound-insulated panels.
