Zabel’s patented flow reduces the trapping of solids in the filter by allowing them to slough off and fall back into the tank for further decomposition.
Slots, rather than mesh screens, provide less surface area for solids to attach, and promote the sloughing action.
Independent research has shown the Zabel A1800 Series filters reduce TSS by 40% in residential applications.
