Working principle
Water with waste particles passes through the filter fleece and enters into the central drum.
From here it flows back into the filter sump. This results in the fleece picking up waste
particles – as this happens, the flow through the fleece decreases and the water level outside
of the drum rises. When the water level reaches the maximum level, a float switch actuates
the f l e e c e d r i v e motor and the dirty fleece roll slowly rotates and a small part of fresh
fleece is loaded on the drum. T h is res u lts in an in c rea se d f lo w t hro ugh t he f il ter

automatically. It will take 3 – 6 months until
the complete fleece is used and has to be
replaced - this depends on the waste
production in the system.
The Fleece is very fine. Even the smallest
particles are removed. The dirt is filtered out
of the system, before it is metabolized
biologically. This eases the workload of
biofilters and the protein skimmers.
The pores of the fleece are even fine enough
to retain many protozoa, like fish parasites in
fresh and saltwater. They cannot pass
through the fleece.
