Oase Biotec 12, 18 and 36
Screenmatic filters available from Swell UK at
amazingly low prices. Prices start from £299.99.
With the new Biotec 12, 18 and 36 Screenmatic, OASE
have once again set new standards for filter
implementation in garden ponds. Simple operation, fast
and clean maintenance with an outstanding filtration
result are unique features of the new Biotec filters.
INNOVATION MADE BY OASE – PATENT PENDING!
Mechanical cleaning
A specially designed sieve, the “Screenex”, retains
all debris particles up to a size of 500 micron, which
are pumped into the filter. After the water flows back
through a special matt it is enriched with oxygen, it
falls into the chamber below, flows through the filter
zones, and then reaches the next filter chamber
(“Individual chamber”).
Biological Cleaning
The nitrosomonas and nitrobacter bacteria present in
the pond water settle and multiply in the oxygen rich
filter zones (blue sponges) and in the oxygen poor
zones (red sponges and individual chamber). In various
biological processes they convert toxic
ammonium/ammonia via nitrite to nitrate and finally to
gaseous nitrogen. The individual chamber situated just
in front of the outlet, is called “individual” because
every consumer has the choice of which filter material
to insert (i.e. OASE Phosless). The chamber is
equipped as standard with Zeolite.
Long service life
With the Screenex filter process happening prior to
the actual filtration, many coarse particles are
removed from circulation and only lightly polluted
water actually reaches the filter sponges. This makes
a longer than average cleaning interval possible.
Unique Advantages
With the new Biotec 12,18 or 36 flow-through filters
SCREENMATIC enables the Biotec 12-18-36 to remove
coarse debris from the pond in a manner that is even
easier and safer.
Water intake, and thus flow
speed as well can be adjusted individually via a
function controller attached to the water distributor
on the SCREENEX.
The SCREENMATIC system can be folded up and out of the
way at a 90 degree angle to provide free access to the
filter sponges, it is no longer necessary to take the
sponges out of the filter for cleaning. The special
tool provided makes it possible to clean the sponges
where they are situated in the filter.
The Oase Biotec 18 is fitted with a 50mm sludge drain
outlet, operated by an internal slide valve making it
easy to drain the filter. The filters can be recessed
in to the ground by two thirds of its depth therefore
making it easier to disguise.
The Oase Biotec 36 has an appropriately dimensioned
SCREENMATIC and a 70mm sludge drain outlet, operated
by an internal slide valve making it easy to drain the
filter.
