BollfilterUSA filters are built into the suction line or pressure pipe.
They protect important parts such as valves, pumps and bearings from abrasive particles and choking.  Depending on type and application, the filter housings are made of either gray cast iron, nodular cast iron, steel or CrNi-steel.
They are designed in accordance with national and international regulations and standards.  Continuous or intermittent operation, manual, or fully automatic cleaning of the filter elements will determine the choice of a filter.
