The automatic backwash unit provides automatic cleaning of the filter screen in Resideo Braukmann backwashing drinking water filters. Backwashing is carried out by opening and closing the drain valve at set intervals, and it can also be started outside the interval. The 5 Nm torque version is intended for F76S, HS10S, F78TS and F74CS / FK74CS filters in sizes 1 1/2"–2". The interval setting is retained even in the event of a power failure, and if a power failure occurs during backwashing, the actuator safely closes the valve using energy stored in the backup capacitor.

Key features

  • Setting of 10 backwash time intervals from 2 hours up to 6 months
  • Manual backwash start via push-button outside the set interval
  • Digital display of the set interval
  • Emergency valve closure in the event of power failure during backwashing (SuperCap backup)
  • Option for external backwash triggering (e.g. differential pressure switch / signal from BMS)
  • Tool-free mounting on ISO flange
