| 20100058927 | AIR FILTER ARRANGEMENT AND A METHOD FOR MANUFACTURING THE SAME - An air filter arrangement comprises an air channel, a first air filter mounted in the air channel, which first air filter comprises a filter frame provided with at least one passage, and a filter body comprising electrostatically chargeable fibres attached to the filter frame. The filter body extends from the filter frame to a position located at a distance from and downstream the filter frame. The air filter arrangement comprises a second air filter comprising a filter cloth which, in a mounted state, is adapted to extend across the air channel such that it is flown through by air flowing in a substantial longitudinal direction in the air channel, and that the second air filter is mounted in the air channel in a position located downstream the first air filter with respect to the flow direction of the air through the air channel. | 03-11-2010 |
| 20100122629 | Triboelectric air purifier - Air purifier containing an air blower and a rotating brush, such brush having long flexible bristles made of a material that is capable of developing negative triboelectric charge. During a part of the rotation cycle, the bristles move across a surface that can accumulate a positive charge. This cause the bristle to charge negatively. The air impurities are attracted to negatively charged bristles and discharged into a collecting bin. | 05-20-2010 |
| 20100251894 | AIR HANDLING DEVICE - An air handling device ( | 10-07-2010 |
| 20110094383 | Electric precipitator and air cleaner having the same - Disclosed herein are an electric precipitator, which efficiently charges dust particles without lowering dust collecting efficiency, although a velocity of an air current is not uniform, and an air cleaner having the same. The electric precipitator includes a charger unit including at least two charge cells to charge dust particles contained in air, and a collector unit to collect the dust particles charged by the charger unit. The at least two charge cells include a first cell, through which the dust particles pass at a first velocity, and a second cell, through which the dust particles pass at a second velocity different from the first velocity. | 04-28-2011 |
| 20110179950 | TUBING AIR PURIFICATION SYSTEM - The invention provides an air purification system in form of tubing, by which particulates of various sizes in the air flow can be collected. The system comprises an air inlet, an air outlet and a particulate removing unit located therebetween, the particulate removing unit including a tubing array of material having low dielectric constant, when an air flow passes through the system electrostatic effect is created between the air flow and the tubing material so as to remove the particulates entrained within the air flow. The invention also provides a method for removing particulates from air flow using the electrostatic effect created between the air flow and said material. | 07-28-2011 |
| 20120097035 | FILTRATION MATERIALS USING FIBER BLENDS THAT CONTAIN STRATEGICALLY SHAPED FIBERS AND/OR CHARGE CONTROL AGENTS - A filtration material comprising a blend of polypropylene and acrylic fibers of round, flat, dog bone, oval or kidney bean shape in any size from 0.08 to 3.3 Dtex. A preferred blend contains about 50 weight percent polypropylene fibers and about 50 weight percent acrylic fibers. The fibers can be blended ranging from 90:10 to 10:90 polypropylene to acrylic. The shape contains 25 weight percent round, flat, oval, dog bone and kidney bean shapes. The fiber blend contains 25 weight percent of at least one size between 0.08 and 3.3 Dtex. Electret fibers incorporated within these blends have 0.02 to 33 weight percent of a charge control agent. These fibers can be used in producing electret material by corona or triboelectric charging methods. | 04-26-2012 |
| 20140305305 | AIR CLEANER AND PILL DISPENSER WITH AIR CLEANER - An air cleaner includes a box and a plurality of absorbers. The box includes a base and a top cover covering the base. The base includes a bottom plate opposite to the top cover. The plurality of absorbers are accommodated in the box. Securing ends of the plurality of absorbers are attached to the bottom plate, and free ends of plurality of absorbers touch the top cover. The plurality of absorbers are configured to move with air flowing in the box to rub against the top cover to generate static charges, and dust particles in the air attaches to the static charges. The box outputs air without the dust particles. | 10-16-2014 |
