4-chamber RV incl. piping and filling package

In this filter series, the chamber walls have been reinforced, and in the XL models additionally with stainless steel threaded rods. As with all EPS filter models, these filters also have a central overflow pipe in the vortex, whereby even more coarse dirt particles are already separated in the vortex. Optionally, these filters can also be operated with a foam cartridge or a sieve filter cartridge. By using the self-cleaning screen pre-filter, these filters have an extended service life and require less maintenance. These filters all work according to the UpFlow system. This means that the water to be filtered always flows through the individual filter media from below, which makes cleaning by backwashing much easier. The UpFlow shafts are additionally sealed and have a cover made of GRP. In the XL models, we have widened the drain shafts (approx. 15 cm) to allow a higher flow. We have equipped this series with a second 110 mm inlet to enable a separate connection of floor drain and skimmer here as well. We have changed the colour slightly (darker green). This allows the filter to integrate even better into the garden landscape. This filter series can be used both as a pump filter and as a gravity filter and is only offered complete with drain piping and filling package. The cover must be ordered separately. Before delivery, all filters are of course checked for leaks.
