The 12″ Zabel A300 filter with a finer 1/32″ filtration makes it the perfect effluent filter for small grease trap applications, dog kennels, laundromats, and other applications where fine suspended solids are present. The A300-12 series provides 1/32” filtration and has been shown to reduce FOG by as much as 50-98%. The A300-12 series offers flow rates of 3000 to 6000 GPD. The A300-12 is also used for onsite wastewater systems which require a finer level of TSS removal. The A300-12 series filter is available in 20”, 28” and 36” lengths.
