RK12-130-P series is a high-flow filter with large areas of internal membrane. Compared to regular RK12 filter, a sharp increase on the membrane area ensures the long-term and efficient filtration. Fit for prolonged and consecutive high-flow coating filtration with less frequency of replacement and slurry waste. Drainable bottom design could be adapted to the recycling of slurry. Unique patented PRF-HC-rolled plus pleated technical design. High efficiency, besides higher flow and higher lifespan.
