Backwashing solenoid valve
In order for the backwashing operation to attain maximum efficiency, during such operation the filter
should not be subject to any filtered water request. To avoid this circumstance, it may be necessary to

Pressure differential switch
A pressure differential switch can be installed to guarantee a fully autonomous, perfect cleaning of the
filter cartridge. The differential switch detects a pressure difference between the filter inlet and outlet. If
this difference exceeds the preset value, a pulse is sent to the filter, which activates the backwashing
procedure. BravoMATIC filters are equipped with an input signal that can trigger the filter backwashing
procedure.
