摘要:
An air-purifying apparatus draws in an airflow from an ambient environment, kills germs in the airflow within the apparatus and expels the airflow purified back into the environment. The apparatus has a housing with an interior chamber. An airflow enters the chamber through an inlet. From the interior chamber, the airflow is expelled through an outlet. The apparatus has an airflow-germ-killing-system that kills germs in the airflow. The apparatus has an airflow-generator which causes the airflow to flow from the inlet to the outlet. In an aspect of the invention, the apparatus has a three-dimensional filter structure that has air-filter-surfaces that define a filter interior region and encompassed by the air-filter-surfaces of the filter structure. The filter is positioned in connection with the inlet so that airflow entering the inlet is dispersed into the housing interior chamber in multiple directions exclusively through the air-filter-surfaces of the three-dimensional filter structure.

An air vent assembly for a ventilation system comprises a main body and a filter assembly. The main body has an airflow conduit with an airflow inlet for connection to an air supply duct and an airflow outlet defining an air supply inlet for a room. Mounting means are provided for securing the main body to a surface such as ceiling so that the conduit is located within a vent aperture of said room. A filter assembly is connected to the main body such that airflow is channelled through the filtration unit prior to flowing through the outlet of the conduit. The filter assembly includes a chemisorption material filter such as an active carbon or an impregnated activated alumina.

The invention relates to a method for controlling the air in a first room during which the room air is supplemented continuously or in recurring time intervals with nitrogen or a nitrogen-containing and carbon dioxide-deficient gas mixture in such a manner that the oxygen portion of the room air is less than 20.9 percent by volume and the carbon dioxide portion of the room air is less than 1 percent by volume. At the same time, at least a low overpressure with regard to an outside atmosphere surrounding the room is set inside the room.

An example wall-embeddable air processing apparatus (100, 200, 300, 400, 450) includes a cabinet (102, 202, 302) having substantially parallel first and second surfaces (110, 210, 310) and a plurality of air filter elements (406a-406c, 456a-456c) located within the cabinet (102, 202, 302). In one embodiment, the air filter elements (456a-456c) are arranged so that filtration surfaces of the filter elements (456a-456c) are substantially coplanar to each other and substantially parallel to the first and second surfaces (110, 210, 310). An intake vent (104, 212, 306) is operatively coupled to the cabinet (102, 202, 302) and configured to enable ambient air to be drawn into the cabinet (102, 202, 302). A fan (454) is operatively coupled to the cabinet (102, 202, 302) and configured to draw the ambient air into the cabinet (102, 202, 302) and to cause the ambient air to flow through the plurality of air filter elements (456a-456c) to generate processed air.

Disclosed is a filter screen and the apparatus for aiding vehicle fuel combustion and purifying exhaust gas using said filter screen which has a metallic screen body treated in a treatment tank containing a discharge electrode plate and a receiving electrode plate both formed of mineral plate so as to have a memorized wave of wave length ranging 5 µm ∼ 20 µm. When placed in various environments, the filter screen is able to negatively ionize the ions in the air passing therethrough by releasing an energy wave motion so as to recover the air into its original pure state thereby improving the quality of the air and enhance the human health.

An air purifying device (10) is provided for removing airborne particles. The device includes a housing (12) including an air inlet and an air outlet. A fan is positioned within the housing for drawing air into the housing through the air inlet and expelling air through the air outlet. A filter assembly (16) is positioned within the housing between the air inlet and the fan. The filter assembly includes a frame (46) and a filter element (48) mounted to the frame. The device has a removable coupler having first and second hangers (18,20). A first elongate hanger support (22) is coupled to the housing and removably extends within the first hanger and a second elongate hanger support (24) is coupled to the frame and removably extends within the second hanger.
摘要:
An air purifier, in particular an electrostatic air purifier, has a housing with an inlet nozzle (3) and an outlet nozzle (4) for an air flow (L) to be purified that is supplied to an air purifying unit (10) arranged inside the housing. The housing (2) of the air purifier (1; 1') is column-shaped and has a substantially air-tight outer sheath (2a). The inlet nozzle (3) of the air flow (L) to be purified is arranged at a first front face (2') of the column-shaped housing (2) and the outlet nozzle (4) is arranged at the other fron face (2') of the column-shaped housing (2). The air purifying unit (10) arranged in the column-shaped housing (2) has a tubular shaped. One inlet (11) of the air purifying unit (10) is arranged in one of its front faces (10'), aligned with the inlet nozzle (3) of the column-shaped housing (2), and one outlet (12) of the air purifying unit (10) is arranged at its other front face (10'), aligned with the outlet nozzle (4) of the column-shaped housing (2) or the air purifier (1; 1').
