The Cetus Sieve is a bow screened pre-filter made using
the latest rotational molding technology. It is made for pre-filtration of any biological filter,
including all pressure filters. Designed to efficiently and
effectively remove large amounts of mechanical waste from a pond, and it
includes the necessary parts to set it up to be gravity-fed or pump-fed. Its robust one-piece mold is totally reliable and comes with flexible boots to help connect it to the pipe work. Comes complete with a 300 micron prefilter included.
Gravity Fed:
This Cetus has a variable inlet height
using the patented Pondflow regulation system. This allows the water
levels within the pond to drop without causing the circulating pump to
be starved of water. It 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 or to a pressurized
filter.
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 back-washing
and maintenance due to heavy solids.
