This cyclone separator connects to the top of a Festool CT 24 36 or 48 extractor forming a stable and highly efficient extraction system. The cyclone design separates and diverts dust into a collection container before the dust reaches the extractor itself. This has several major benefits: 95% of larger particles and 80% of the fine dust never reach the extractor hugely reducing the workload of the main filer. The filter bag inside your extractor takes much much longer to fill making a genuine cost saving. There is no loss of suction as the CT-VA connects directly to your extractor. This is the optimum way to deal with high volumes of waste.
