Highly effective flow-through filter for ponds up to 140 m3, which requires very little maintenance because the coarse dirt is separated before entering the filter and it has a long service life: The double-sealed motor ensures a much longer service life. The adjustable automatic cleaning system ensures an efficient separation result. A water distributor without bottlenecks prevents blockages. Innovative dirt barriers prevent the filter from being washed out. The cleaning is very convenient: The filter belt cleans itself and the filter sponges are cleaned directly in the filter.
