Ideally suited as ventilation when installed at the end of a drinking line (up to 20 m).
The vent is made of durable plastic. The breather tube is made of a transparent material with a red ball floating inside, showing the height of the water column.
A special drain plug allows water to be drained off for rinsing. A valve protects the drinking system from ventilation. This is particularly useful when the drinking system is connected to a pressure regulator.
