2. Working principle
The polluted water flows into the dirty
water chamber and passes the filter
fleece. From here it flows back into the
filter sump. If the fleece is loaded with
dirt, the flow through the fleece
decreases and the water level in the
dirty water chamber rises. If it reaches
a certain level, a level switch starts the
motor and a small part of fresh fleece
is loaded on the grid. Fully
automatically. It will take 4 – 6 months,
depending on the waste production in
the system until the complete fleece is
used and has to be replaced.
The Fleece is very fine. Even smallest
particles are removed. The dirt is
filtered out of the system, before it is
metabolized biologically. This relieves the biofilter and the protein skimmer in seawater.
The pores of the fleece are even fine enough to retain many protozoa, like fish parasites in fresh and
saltwater. They cannot pass the fleece. This is unique.

Features of the Rollermat:
Efficient mechanical filtration by fine
filter fleece
Automatic transport of the fleece.
Easy changing of the used fleece roll.
The rolls are easy to change, up to 100 m
length.
The roll is 10 cm wide, for flow rates up
to 2000l/h, depending on the water
quality.
Minimum power uptake. Average below 0,1w.
12V safety voltage
The fleece is transported from the releasing roll to the accepting roll. The rolls are driven by gear
wheels by gear wheels. I f the accepting roll is full – or the releasing roll empty, it can be taken out of
the filter easily. Both parts can be separated and the fleece can be discarded.
