Abstract: A filter for a respirator mask or other filtering applications, in which the filter comprises a filtering medium which may enhance performance of the filter, such as by providing enhanced filtration and/or lower resistance to airflow (e.g., lower respiratory resistance for a wearer of the respirator mask). The filtering medium may comprise active particles (e.g., activated carbon) that are derived from a polymeric precursor (e.g., polyvinylidene dichloride (PVDC)), impregnated with additives (e.g., metals and triethylenediamine (TEDA)), substantially uniform in size (e.g., monodispersed), and/or loose.

Abstract: A dust filter mounted in a semiconductor waste gas treatment equipment comprising a housing having a chamber in the housing for passing a gas containing a water molecular and a dust through; and one or more main filtration boxes which can be implanted into the chamber by withdrawing way. One or more capturing rings and a filtering cotton for filtering the water molecular and the dust from the gas being disposed in the main filtration box, and the gas being sequentially passed through the capturing ring and the filtering cotton. It is an objective to solve a problem saying that it is not easy to clean the conventional dust filter because the structure of it is too complex.

Abstract: Various embodiments of the present disclosure provide a portable industrial air filtration device employing an annular dual filter assembly to capture and remove impurities from the air surrounding the air filtration device, enabling the air filtration device to quickly and efficiently improve the quality and safety of the air. The air filtration device includes a two-piece housing including a lower housing component and a locking cover removably attachable to the lower housing component. The dual filter assembly is mounted within the housing between the locking cover and the lower housing component, and includes a removable self-supporting outer pre-filter surrounding a separately removable inner HEPA filter. The pre-filter initially filters the surrounding air by capturing relatively large or coarse impurities, and the HEPA filter further filters the air pulled through the pre-filter by capturing relatively small or fine impurities.

Abstract: Air filtering devices are disclosed that contain a first filter cartridge having a cartridge inlet and a cartridge outlet and a curved filter bed having a concave surface disposed such that air to be filtered passes through the inlet, the curved filter bed, and the outlet. The air filtering devices also contain a blower assembly having a blower inlet in fluid communication with the cartridge outlet and a blower outlet, the blower assembly includes a motor proximate to the concave surface of the curved filter bed. The motor has a rotational axis such that the rotational axis is adjacent to the center of curvature of the curved filter bed. The air filtering device may be used in powered air purifying respirators.

Abstract: A purification column is provided in which fluid is purified by flow through a purifying component. The column includes an annular wall defining a bore which, in use, contains the purifying component. The column further includes an inlet port to the bore comprising a first aperture through the annular wall, the inlet port being adjacent one end of the column. The column further includes an outlet port from the bore comprising a second aperture through the annular wall, the outlet port being adjacent the same end of the column as the inlet port. The column further includes a flow guidance device within the bore and removably connected to the inlet and outlet ports for guiding the fluid to the purifying component from the inlet port and for guiding the fluid from the purifying component to the outlet port. The flow guidance device maintains separation of the fluid flows to and from the purifying component.
