This study was the development of air-cleaner for railroad passenger car. the characteristic of air-cleaner is to improvement of in door air quality and easy of maintenance. the air-cleaner is applicated to roll filter system. advantage of roll filter is to reduce time and cost of maintenance. The developed air-cleaner was installed to the railroad passenger car, and then has fieldtested for roll filter system"s performance. the result of field-test performance was average Eff. 32% that is average of several days" measurement data.

The indoor air quality guideline of public transportation means was prepared recently. therefore we consider a countermeasure for the indoor air quality improvement of public transportation means. In this work, air-cleaner with roll filter system which developed alternative of indoor air quality guideline. The develpoed roll filter system is two function. the first function harmoniously circulated to heating and cooling air through HVAC system and secondary function removed PM(particluatie matters) which re-scatting to passenger"s movement and suppled from outdoor air. Filter media of roll filter system select optimum electret mesh filter out of many filter media. Selected filter media was performanced tests of pressure drop, collection efficiency and dust holding capacity. Finally developed roll filter system was performanced bench test.

Management of indoor air quality is important because of large proportion of time spent indoors. Recently, new air cleaning system in the railway cabins was developed by Korea Railroad Research Institute funded from Korean government. New cleaning system is roll-filter type which collects PM10 particle in the cabin. In this study, we studied collection efficiency of double layered non-woven filters for subway cabins. Double layered non-woven filter was arranged for four different cases, single layer filter, double layer filter(at 0㎜ gaps between two filter), double layer filter(at 5㎜ gaps between two filter), double layer filter(at 10㎜ gaps between two filter). We found that collection efficiency was increased when the gap of layer increased.
