The 4″ Zabel A1800 filter used to be designed for residential applications with float rates as much as 800 GPD. The cartridge design allows for simple installation and maintenance. All A1800 series filters feature a locking tab that securely locks the filter into the tee. With 1/16” filtration, this filter is to be had in 18” and 22” lengths. The 22” A1800 comes with a built in gas deflector.
Zabel’s patented float reduces the trapping of solids within the filter by letting them slough off and fall back into the tank for further decomposition.
Slots, fairly than mesh screens, provide less surface area for solids to glue, and promote the sloughing action.
Independent research has shown the Zabel A1800 Series filters reduce TSS by 40% in residential applications.
Zabel 4×18 and 4×22 filters can be utilized with ANY 4” tee, including our PL-68 tee and our Versa-Tees.
One Peice Design: Now made of polypropylene for extra strength, filters are no longer snapped together, and won’t break when servicing.
