  • BOLLFILTER Automatic Type 6.18
    Nominal diameters: DN 50 - DN 1000/2" - 40"<br />Backflushing: actuated by differential pressure or time control<br />Pressure stages: PN 6 - PN 16<br />Grade of filtration: 25 micron - 5000 micron...

  • 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 backflushing 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

  • BOLLFILTER Automatic Type 6.46/ 6.48
    DN 50 - DN150<br />Backflushing: continuous<br />Material variations filter housing: nodular cast iron<br />Pressure stages: PN 10<br />Grades of filtration: 25 micron...

  • This compact automatic backflush filter type 6.46 / 6.48, for horizontal or vertical installation, is used primarily in lubricating oil systems. The turbine driven, continuously rotating flushing mechanism works almost without wear, even with low quantities and pressure levels. The fine filter candle are resistant to differential pressure up to full operating pressure level. The continuous axial- and cross-flow backflushing system allows cleaning over the entire length of the candle. In addition, a safety screen and an overflow protection ensure safety in case of emergency

  • BOLLFILTER Duplex Type BFD-P
    Nominal diameters: DN 25 - DN 150<br />Switch-over: ball valve<br />Material variations filter housing: carbon steel, stainless steel; non-welded<br />Pressure stages: max. PN 100<br />Grades of filtration: 0.5 micron - 250 micron...

  • Duplex filters comprise two filter housings. One chamber of the filter is on duty whilst the other clean half is on standby. When the contamination level exceeds a preset tolerance level, the flow can be switched manually to the cleaned half of the filter without any pressure shock. The contaminated filter element is cleaned whilst the process continues. Change-over is performed by a cylindrical cock valve or double stage three-way ball valves. The design prevents both filter chambers from being shut off at the same time.
