The internai components are therefore always made of stainless steel. The fully automatic back-flushing of the filter element is very efficient. Axial- and cross-flow backflushing is generated with filter candles open at...

untitled table.main {} tr.row {} td.cell {} div.block {} div.paragraph {} .font0 { font:6.00pt "Arial", sans-serif; } .font1 { font:7.00pt "Arial", sans-serif; } On the BOLL automatic filter TYPE 6.18.2, rotating flushing arms are located above and below the filter element. The re-designed filter candles are backflushed alternately from above and below within one cleaning cycle , without interrupting of filtration and by using the internal medium. The hydrodynamic element, positioned internal of the filter candle, increases the flow velocity in addition and thus optimises the effectiveness...

It essen-tially consists of a supporting body and a filter media. Vari-ous designs provide differing sized filtration surfaces. The required degree of filtration and cleaning can be achieved for every medium with the ideal combination of core components. Type...
