The backflow preventer is suitable for residential buildings, industrial and commercial purposes. Protects drinking water systems against back pressure, back flow and back syphonage. This is most often used when combining water abstraction from the water line and boreholes.

Compact design with easy service and easy access to all internal components. The special design prevents water from "standing". The preventer has a low pressure drop and high flow rate at a low noise level (group 2). It is certified for use in drinking water and meets KTW recommendations for potable water

How does the separator work?

BA type backflow preventers are divided into three pressure zones. The pressure in zone 1 is higher than in zone 2, which in turn is higher than in zone 3. A discharge valve is connected to zone 2 which opens at the latest when the differential pressure between zones 1 and 2 drops to 0.14 bar. The water from zone 2 discharges to atmosphere, both check valves close and therefore separate zone 2 from zone 1 and 3. In this way the danger of back pressure, back flow or back syphonage into the supply network is prevented.
