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. Description and specifications can be viewed or downloaded.
An example of using a 2" SDF Element in OEM Dismantled Filter is shown on the right. Cleaning is manual: The filter case is opened by releasing the clamp and the element is pulled out for manual easy wash.
The SDF™ Elements can also be used as "Open Filters" by dipping it in a reservoir or river and pumping water by suction from its inner chamber.
