Abstract
In this study, a electrostatic filter which could be applicable to road environment was developed and evaluated in adsorption capacity. The evaluation were performance for removal by particle size and adsorption amount by pressure using ASERAE 52.1 and 52.2. The range of size for removal test was 0.3 μm~10.0 μm which had 12 steps. The filter showed 91.3% removal efficiency from 2.5 μm and under the size, average 53.5% proportional to decreasing size value. The weight removal was 96.7% from 22.6 mmaq, initial pressure to 35 mmaq, end pressure with 715.9 g/m2, the adsorption amount. The shape of isotherm was expressed as Langmuirâs one. After washing saturated filter with dust to end pressure, the initial pressure and adsorption amount of the filter showed a light drop with no removal efficiency decline. Key words: Fine Dust, Langmuir Isotherm, Filter Panel, ASHRAE 52.1, ASHRAE 52.2
