Swell Biotec 18, Filterforce 16000, Evolution Aqua EVO UV 55 Watt Kit

New from Swell UK, a high quality pump, filter kit and UVC for your garden. Each item is well known in its own right, but now as a limited offer, we have combined the Oase Biotec 18, Bermuda Filterforce 16000 and the Evolution Aqua Evo UV 55 watt, in a kit just for you, at a very special price.

With the new Biotec 18 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.

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.

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.

The Oase Biotec 18 is fitted with a 50 mm 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.
