SEPP Safe vacuum braker DB, form A2 (female x male thread)

SEPP Safe vacuum braker DB, form A2 (female x male thread)


The SEPP Safe 8222 vacuum braker type DB has an elastic membrane that closes the air gaps when water flows. When the waterflow is cut, or when there is underpressure, the air gaps open to allow air to enter the pipe section.

  • a DP vacuum braker protects against suction at underpressure, not against counterpressure
  • downstream,only free flow (pipe/hose) is alowed
  • it is not alowed to place a valve downstream from the vacuum breaker
  • the vacuum braker must have at least the same size (DN) as the upstream pipe
