Product Information
Sand filters must be periodically backwashed in order to loosen up the sand and to eliminate filtered dirt through the waste system. This requires, among other things, the hydraulic current of the filter circulation pump to be reversed through the filter housing.
After backwashing, fresh water must be fed into the system in order to reestablish the original water level. This is best done automatically with our BADU-Niveau-Control BNR 55 or BNR 200 S.
