VAG NOVA NIRO 365 Standpost Hydrant

The reliable one


The NOVA NIRO 365 sets new standards in terms of reliability, drinking water hygiene, ease of operation, resistance to corrosion, wear and weather and freedom from maintenance of its actuator – 365 days per year and longer!

The system of the maintenance-free encapsulated bearing is a novelty in the world of hydrants. The innovative bearing has been optimised for drinking water hygiene, is easy to operate, maintenance free and will stay that way.


Freedom from maintenance which eventually saves lives.
