Purgex DN60
PURGEX DN60 protects mains DN60 up to 200. The device evacuates great air amount during the filling of the main. Allows the inlet of great air amounts (in order to avoid a vacuum effect) during the emptying of the main.
For Pipes DN60 up to 350. Evacuates small air amounts that are accumulated in the high points of the main during normal working conditions.
