摘要:
La présente invention se rapporte à un filtre microbicide (100) pour le traitement de l'air, du type comprenant dans le sens (A) dévolu d'écoulement de la veine d'air susceptible de le traverser, une couche de filtration, un filtre HEPA. Selon l'invention, la couche de filtration (110) contient un agent bactéricide et/ou fongicide, et le filtre HEPA (130) est plissé en étant appliqué contre une seconde couche de filtration (150) plissée disposée en aval, de manière à éviter la mise en contact mutuelle de ses plis. La conjugaison de l'action de la couche imprégnée et du filtre HEPA permet d'inhiber ou de tuer par contact toutes les particules vivantes qui pénètrent dans le filtre microbicide. Le filtre HEPA est maintenu appliqué de manière stable dans sa géométrie plissée contre la seconde couche de filtration, si bien que les performances de filtration ne s'altèrent que progressivement.

The present invention also relates to an air cleaning filter including a carrier having kimchi lactic acid bacteria and disinfectant coated thereon to have an effect of removing or sterilizing bacteria, fungi, and virus from the air. The present invention also relates to an air cleaning filter further includes fermented Ecklonia cava extract. The air cleaning filter according to the present invention is produced by a method including the step of coating and immobilizing kimchi lactic acid bacteria and disinfectant on a carrier, or the step of coating and immobilizing fermented Ecklonia cava extract on a carrier as necessary. Or, the air cleaning filter of the present invention includes the step of coating a coating solution on the carrier, the coating solution including kimchi lactic acid bacteria, disinfectant, optionally fermented Ecklonia cava extract, and a binder selected from a group including silicon modified acryl resin, silicon modified epoxy resin, urethane resin, acryl resin, and silicon resin, and, the step of drying the carrier coated thus, whereby permitting to clean air effectively by removing or sterilizing bacteria, fungi, and virus from the air.

The present invention provides a device for detection, collection, containment, neutralization, and elimination of aerosolized contaminants, comprising a lid 102 that fully covers an edge of a container for containment of exiting aerosolized contaminants, with the lid 102 having housing 110 for accommodating an article 114. The housing 110 comprising a top vent 118 aligned along atop of a bottom vent 112, with the top vent 118 optionally smaller than the bottom vent 112, and with the housing 110, the top vent 118, and the bottom vent 112 located normal to a natural vertical upward move of the aerosolized contaminants. The aerosolized contaminants are detected, collected, contained, neutralized, and eliminated and sanitized by the article within the housing 110, allowing only uncontaminated air out of the top vent 118 through a natural upward movement of the aerosolized contaminants via the force of the flush.
摘要:
Filters, methods, and an apparatus for filling housings and both encapsulated porous and non-porous spaces with contaminant control media for placement in electronic enclosures, such as disk drive enclosures, are disclosed. In one embodiment, a filter assembly includes a housing comprising an internal cavity configured to receive contaminant control media, a fill port in communication with the internal cavity, and an opening in communication with the internal cavity, and filter media at least partially covering the opening; and contaminant control media occupying the internal cavity. Contaminant control media is deposited within the internal cavity via the fill port by means of creating a negative pressure within the internal cavity. The application of a partial vacuum facilitates movement of the contaminant control media into the internal cavity and minimizes the contamination of the filter, housing, and work space common to other loose fill filling methods. Other aspects and embodiments are provided herein.
摘要:
Embodiments of the invention generally provide an apparatus and method for certifying a filter in a containment system without decontaminating the containment system prior to certification. The apparatus generally comprises a valve assembly selectable between at least three operational states. A first state prevents flow from prevents flow through a port of a housing. A second state fluidly couples the port to test equipment necessary to test a filter disposed within the housing. A third state seals the port but fluidly couples the test equipment to a decontamination system.
摘要:
The present invention relates generally to a filtration article, such as a protective facemask, a method for using a filtration article, and a method for preparing a filtration article. In particular, the invention relates to a protective facemask that cost-effectively offers a broad spectrum of antimicrobial protection through the use of fibers treated with one or more oligodynamic metal and/or salt of an oligodynamic metal.
