A new super cleaning equipment of a closed space with photoelectric diffusion charging was developed. The newly developed device has UV shield plate between the charging/collecting space and cleaning space to protect the cleaning space from the UV irradiation. The particle removing rate by the equipment was experimentally and theoretically investigated. The basic equations expressing the diffusion charging and electrophoresis of particles in the charging/collecting space was derived for polydisperse aerosols. By these basic equations, the collection efficiency of the charging/collecting space was found to depend on three dimensionless parameters. The values of the dimensionless parameters required to obtain collection efficiencies of 90 and 99 % were presented graphically. Some of the calculated results were verified by the experiments.
