Abstracts
Pressure drop and particle removal efficiency of two commercial fibrous medium filters were measured with
20~1,000 nm sized aerosolized KCl particles. Pressure drop and particle removal efficiency were also theoretically
predicted and the results qualitatively agreed with the experimental data. For this given particle removal efficiency,
a filter design method for obtaining minimum pressure drop (and therefore minimum fan power) was suggested in
this study by selecting solidity and fiber diameter as parameters. Therefore, by carrying out theoretical and experimental
approaches together, this paper introduced a way of finding conditions for low pressure drop and high performance
of a fibrous filter, especially if the filter would be used in mechanical ventilation system.
