The analytical investigations of the filtering efficiency with multi-layered stainless screen filter, which is designed to generate swirling stream of micro metal dust from industrial manufacturing processes, were conducted. Compared to general filter dust collecting using bag filter, it can be expected that the metallic screen filters in this study enable the higher dust collecting efficiency of a system to be maintained even under harsh filtering conditions. The CFD analysis includes dust particles behavior, filtering efficiency, and pressure loss in the flow-field. The results show that the proposed 16 layered screen filter is able to collect 10 microns metal dust up to 97 % under 487.84 ㎩ differential pressure.
