BOLLFILTER automatic filters and strainers are automatic backwash units for the filtration of low-viscosity liquids. The filters guarantee uninterrupted and trouble-free operation of industrial or maritime plants and engines. Your advantage: With these reliable filter systems you also extend the maintenance intervals, thereby keeping your operating costs low and avoiding unwanted production shutdowns.
The medium flows through the filter element either from inside to outside or from outside to inside. Here the dirt particles are retained and the cleaned medium reaches the filter outlet. When the differential pressure reaches a certain value, a signal is transmitted from the differential pressure indicator to the control unit, which automatically triggers the backwashing process.
When the differential pressure reaches a certain value, the differential pressure indicator transmits a signal to the control system, which automatically triggers the backwashing process. During backflushing, the dirt particles are flushed off of the filtration surface by filtered fluid reversal of flow (own medium or through external flush medium, compressed air or service water).
The following automatic filters can be used, depending on the flow rates, rate of filtration and fluids. Here you find an overview of our automatic backwash filters (self-cleaning):
