Publication number: 20140020561Abstract: Segmented stackable filter assembly for filtering a gas and method of manufacturing same. An exemplary embodiment of the segmented stackable filter assembly comprises a plurality of filter segments stackable end-to-end for varying filtration capacity of the stackable filter assembly. Each filter segment includes an annular outer wire mesh and an annular inner wire mesh spaced apart from the outer wire mesh to define a gap therebetween containing filter media. The inner wire mesh defines a central air flow passage axially through the filter assembly. A lower end plate has an opening for receiving a neck portion upwardly projecting from an adjacent upper end plate, so that both filter segments are prevented from laterally moving relative to each other. A fan assembly is supported by the neck portion for suctioning the gas through the plurality of filter segments.Type: ApplicationFiled: July 18, 2012Publication date: January 23, 2014Inventor: Glen Aery

Patent number: 8617300Abstract: The invention relates to a filtering media having a photocatalytic action which has a thickness of at least 2 mm, which is homogeneous and which is devoid of orifice apparent to the naked eye, comprising a felt of inorganic fibers, the fibers of which are coated with a coating comprising a catalyst having a photocatalytic action, said felt exhibiting a weight per unit area of between 30 and 80 g/m2, said coating representing 5 to 80% of the weight of said media, said media exhibiting a gas pressure drop of less than 150 Pa at 1 m/s in unpleated condition. This media is intended to be incorporated in a purifier of gas, such as air, furthermore comprising a system for illuminating said media with UV radiation. The media exhibits an excellent purification efficiency and a very low pressure drop.Type: GrantFiled: July 17, 2008Date of Patent: December 31, 2013Assignee: Saint-Gobain Quartz S.A.S.Inventors: Jean-Paul Riviere, Paul Sargood, Laurent Molins

Publication number: 20130333567Abstract: This disclosure describes embodiments of an air treatment apparatus that stimulates formation of large moisture droplets from small moisture droplets found in air flowing in power generating systems to a turbo-machine. In one example, the embodiments generate a field that promotes contact between the smaller moisture droplets. This contact can increase the size of moisture droplets to facilitate condensation of moisture out of the air.Type: ApplicationFiled: June 13, 2012Publication date: December 19, 2013Applicant: General Electric CompanyInventors: Abhijeet Madhukar Kulkarni, Martin Gregory Hatfield, Richard Michael Ashley Mann

Publication number: 20130291735Abstract: A device and method for air purification used in cooling, heating and air ventilation systems. The device has at least one UV light source positioned on an inside portion of a movable access panel so that it moves with the access panel from a first position where the UV source directs UV light towards the inside of the system to purify the air stream inside and to remove contaminants from the surfaces inside the system, to a second position where the UV source directs UV light towards the space surrounding the system so that it purifies the air in the room where the system is mounted.Type: ApplicationFiled: November 18, 2011Publication date: November 7, 2013Applicant: OY HALTON GROUP LTD.Inventors: Andrey V. Livchak, Rick A. Bagwell

Publication number: 20130239803Abstract: A method for reducing airborne contamination within a home includes installing an air-pressure control system within a window of the home, and drawing air from outside the home through the system inlet and an airflow path through the system. As it passes through the airflow path, a germicidal radiation chamber with a UV light source sterilizes the air. Additionally, filter(s) may clean the drawn air by removing particulates from the air as it passes through the filter. The method may then introduce the sterilized/cleaned air into the home through the system outlet. The sterilized/cleaned air may displace an equal volume of contaminated air within the home.Type: ApplicationFiled: February 28, 2013Publication date: September 19, 2013Applicant: AMERICAN INNOVATIVE RESEARCH CORP.Inventor: David W.

Patent number: 8535426Abstract: An apparatus, system, and method are disclosed for removing ethylene from a gaseous environment. Ethylene is a gaseous growth hormone produced by plants that triggers the ripening of some flowers, fruits, vegetables, and other plants. The apparatus includes an ethylene filter and a composition. The filter includes a frame and a trapping medium. The composition is attached to the trapping medium of the ethylene filter. The ethylene filter is positioned within a gaseous environment and is configured to encounter a gas flow within the gaseous environment. The composition contains at least some titanium dioxide which is configured to attach to the ethylene as the gas flow moves through and around the ethylene filter. In this manner, some ethylene may be removed from the gaseous environment.Type: GrantFiled: August 22, 2011Date of Patent: September 17, 2013Inventor: Lawrence R. Sadler
