INNOVAQUA - Percolating Filter

The percolating filter is a gravitational open filter, where there is a perfect contact between water, air and filter media. Thanks to the rotary spray system, the water is distributed evenly throughout the filter section and falls freely across wetting the filtering surface, taking full advantage of the filter media volume. The side entries of the percolating filter are aerators that through natural convection improve the oxygenation of all filtering bedding. That is why, this is a system with no restriction of oxygen, but does not keep the recirculation pressure.
