Abstract:
An electro-kinetic air mover for creating an airflow using no moving parts. The electro-kinetic air mover includes an ion generator that has an electrode assembly including a first array of emitter electrodes, a second array of collector electrodes, and a high voltage generator. Preferably, a third or leading or focus electrode is located upstream of the first array of emitter electrodes, and/or a trailing electrode is located downstream of the second array of collector electrodes. The device can also include an interstitial electrode located between collector electrodes, an enhanced collector electrode with an integrally formed trailing end, and an enhanced emitter electrode with an enhanced length in order to increase emissivity.
Abstract:
A bipolar ionization tube includes a cylindrical glass tube having an open end and closed end. A cathode is positioned within and is circumscribed by an interior surface wall of the glass tube. An anode circumscribes an exterior surface of the glass tube, where the anode is adapted for electrical connectivity with a first conducting terminal of a power supply. An electrically insulated end cap has a groove for receiving the open end of the glass tube, and the end cap is secured to the glass tube with at least one sealant. An elongated conducting terminal having a first portion extends through the end cap and is adapted for electrical connectivity with a second conducting terminal of the power supply. A second portion of the conducting terminal extends into the glass tube and is configured for electrical connectivity with the cathode.
Abstract:
The present invention provides a method and apparatus for removing chemical sterilant molecules from a medium, such as a carrier gas. In one embodiment, the apparatus includes a housing that defines an internal cavity. The housing has an inlet and an outlet fluidly communicating with the internal cavity. An electrode is dimensioned to be received in the internal cavity of the housing. The electrode is made of a material that is chemically active with respect to molecules of a chemical sterilant and conductive to electricity. The electrode is connected to a source of an electrical charge such that an electrical field gradient is formed in a region of space surrounding the electrode. The electrical field gradient is operable to force the chemical sterilant molecule toward the electrode.
Abstract:
An electrically enhanced air filter apparatus for filtering particles from moving air is described. The apparatus includes a filter arranged so particles approach the filter a filter speed and pass through an ionizer at an ionizer speed, and is configured so the filter speed is less than the ionizer speed. The ionizer is arranged to guide the moving air in an ionizer airflow direction and generates an ionizing electric field having ionizer field direction substantially perpendicular to the ionizer airflow direction.

Abstract:
In one aspect of the invention, a plasma reactor is arranged to treat aerosol particulates in a fluid stream passing through the reactor. The plasma reactor includes a plasma chamber having a self-cleaning electrode. The self-cleaning electrode is configured to clean various residues from the electrode without need to open or otherwise service the unit. In another aspect, the invention comprises a carbon-based pre-filter arranged to filter in flowing air to reduce the amount of silicone-based contaminant in the air flow before the air reaches the ionization chamber.
