The BOLLFILTER automatic Type 6.18.2 Heavy Duty is a backwashing self-cleaning filter, which has been designed for filtering water with high particle contamination. Typical fields of application for this BOLLFILTER are non-prefiltered river water and highly fibre-laden process water.
The principle behind it: Dual filtration, dual flushing!
The proven principle of dual filtration (where cross and counterflow backflushing is generated) has been supplemented by an efficient dual backflush function. The elements are open at both ends allowing the water to flow through from each end. Due to their length and increased diameter, their filter surface area is especially large.
