Type: 6.18
Application : Water
Maximum Capacity: 9000 m3/hr
The economic operation of modern factories, in which large volumes of cooling water in open or closed cooling circuits, process water and waste-water are used, places the highest requirements on the filtration process. We have numerous references for Type 6.18 filters.
The BOLL Automatic Filter SELFCLEAN types 6.18 and 6.19 fulfill these requirements in optimum fashion. With their unique bipolar mode of functioning in filter and backflush modes, they set the process quality and performance standards in the field of water filtration.
