Abstract: An apparatus for removing respirable aerosols (typically within the size range of about 0.1 to about 2 microns in diameter) from air comprises a housing and a chamber demountably coupled to the housing, the chamber having a dielectric material forming a packed bed within a charged bed region and apparatus for charging the aerosols in the air so that they may be removed when contacting the dielectric material in the bed region. An indicating device is provided to signify when the dielectric material is contaminated and should be renewed. The chamber may comprise cardboard or plastic coated with a conductive material and can be disposed of along with the contaminated material.A method for removing the respirable aerosols from air is also disclosed.

Abstract: An apparatus for removing respirable aerosols (typically within the size range of about 0.1 to about 2 microns in diameter) from air comprises a housing and a chamber removably coupled to the housing so as to extend outwardly therefrom. The chamber contains a dielectric granular material forming a packed bed within a charged bed region and an apparatus spaced from the bed region for charging the aerosols in the air so that they may be removed when contacting the dielectric material in the bed region. The granular material is retained between two spaced apart gas permeable electrodes disposed adjacent an outlet end of the chamber and the charging apparatus is disposed adjacent the inlet end and is defined by a gas permeable support member having charging electrodes supported thereon or formed as an integral part thereof.

Abstract: Material comprising particulate matter is atomized and coated on a surface of an object by delivering the material to a surface of a spinning atomizer from a non-rotating delivery means preferably situated within the volume defined by the atomizer. The material is atomized by being thrust from the atomizer surface and at least a portion of the atomized material impacts the surface being coated. The method is particularly applicable to coating surfaces wherein abrasive material is atomized, since a seal between the non-rotating delivery means and atomizer is not needed, and wherein space limitations are imposed on the configuration of the atomizer. Further, a potential difference may be established between the atomized material and surface to be coated whereby an axial flow of material from the surface of the atomizer may be effected.
