The main field of application for this BOLLFILTER Automatic is water filtration. The internal components are therefore always made of stainless steel. The fully automatic black-flushing of the filter element is very efficient. Axial- and cross-flow backflushing is generated with filter candles open at both ends - the bipolar functional principle.
