SDF Rotary Filters are semi-automatic filters: back-flush cleaning is maintained simply by opening the drain valve and rotating the filter`s body a couple of times around its center-tube. There is no need to dismantle the filter or to replace any cartridge. This advanced design provides an infinite number of self-cleaning cycles, each made by a reverse flow of clean water ("back-flush").

The Disk Stacks produced for variety of existing OEM filter cases. These stacks, "SDF™ Elements", are permanent non-disposable elements that can be cleaned time and again. They are custom made in several dimensions for variety of flow rates and in any mesh grades.
