The Cetus sieve
is a totally new,
bow screen
pre-filter, made
using the latest
rotational molding
technology. With all
of its benefits and
build quality, it is
undoubtedly the best
of its kind on the
market today in
terms of quality and
performance! It is
designed to
efficiently and
effectively remove
large amounts of
mechanical waste
from a pond. It can
be set-up gravity or
pump fed and has
many benefits over
the original bow
screen technology.
This Cetus has a
variable inlet
height using the
unique patented
Pondflow regulation
system – for use
when gravity fed.
This allows water
levels within the
pond to drop without
causing the
circulating pump to
be starved of water.
The Cetus will allow
a skimmer or a
bottom drain to
accept vast amounts
of waste without
excessive cleaning
needed to be carried
out. The water must
then be pumped to
either a normal
filter above pond
level (Nexus
Eazy/Eazy
Pod) or to a
pressurized filter.
If pump fed, the
sieve is placed
above pond water
level and then the
exit water is
gravity dropped into
your main filter.

It is advised that
all pressurized
filters be
pre-filtered using a
Cetus to reduce
excessive
backwashing and
maintenance due to
heavy solids.

pump fed (please
specify)
