Patent number: 8409336Abstract: An air filter system (10) has a filter housing (11), an air filter media (12), and an electrical circuit (13) electrically coupled to the media. The filter media consists of a pleated air filter material (23) with front pleat apexes (25) and rear pleat apexes (26) which are coated with an electrically conductive material to form front vertical strips (27) and rear strips (28). The electrical circuit includes a positive front electrical contact (30) and a rear electrical contact (31). The front electrical contact has a rear surface (30?) in electrical contact with an elongated front electrical contact bar (33), oriented horizontally across and in electrical contact with the filter front strips of conductive ink. Similarly, the rear electrical contact has a front surface (31?) in electrical contact with an elongated rear electrical contact bar (34), oriented horizontally across and in electrical contact with the rear strips of conductive ink.Type: GrantFiled: August 13, 2010Date of Patent: April 2, 2013Assignee: Hunter Fan CompanyInventors: Stephen M. Gatchell, Benjamin David Freeman

Publication number: 20090229469Abstract: An air purifier (10) is disclosed including an electrically motorized fan (12). The air purifier includes a manual touch pad controller (16) which allows the manual operation of the air purifier and a computer interface which allows the user to control the fan speed through a personal computer (18). The software can allow the user to utilize the computer to automatically turn the air purifier on or off, change the fan speed, indicate the percentage of filter life remaining, and provide a mode of operation which includes a timer mode, wake mode or snooze mode that is in sync with the computer. In an air purifier wake mode, the air purifier is turned “on” whenever the computer is in an awake mode and turned “off” whenever the computer is in a sleep mode. In an air purifier snooze mode, the air purifier is turned “on” whenever the computer is in a sleep mode and turned “off” when the computer is in an awake mode.Type: ApplicationFiled: March 11, 2009Publication date: September 17, 2009Applicant: HUNTER FAN COMPANYInventors: Glennbruce S.

Patent number: 7258715Abstract: An improved filter element for use in an electrostatic precipitation air cleaning device, the filter element including rod electrodes arranged through a stack of alternating fluted plastic sheets and plate electrodes. Successive plate electrodes are arranged to make contact with an alternating one or the other of the rod electrodes. The plate and rod electrodes may be composed of high impedance materials such as paper and plastic, respectively. An arrangement for removably inserting a filter element into an air cleaning device is provided. The arrangement also removably provides electrical connectivity between the filter element and the air cleaning device. The filter element can thus be readily removed and re-installed by a user.Type: GrantFiled: July 22, 2004Date of Patent: August 21, 2007Assignee: Kaz, IncorporatedInventors: Paul E. Cox, Stephen M. Gatchell, James J. Best, Steven Vordenberg, Boris Kontorovich, Kevin Lozeau

Patent number: 7014686Abstract: An air cleaner electrode assembly includes an elongated collector electrode and a plurality of elongated discharge electrodes arranged around the collector electrode. A fan may move air in a direction parallel to a length of the electrodes. The collector electrode may have a plurality of distinct faces where at least one discharge electrode is associated with a corresponding face. A cleaning shuttle may be configured to ride on and remove debris from the elongated electrodes. A voltage differential across the electrodes and the fan speed may be adjusted independently of each other.Type: GrantFiled: March 4, 2004Date of Patent: March 21, 2006Assignee: Kaz, Inc.Inventors: Stephen M. Gatchell, Chi-Hsiang Wang

Patent number: 6361590Abstract: A portable air cleaner including a housing defining an air inlet, an air outlet, and an air flow path therebetween, a centrifugal blower retained within the air flow path and operable to draw air through the inlet and a filter retained within the housing and disposed to transmit air circulating in the air flow path out of the outlet. Also included is a conveyor surrounding the blower and defining a scroll shaped passage having one end disposed to receive air from the blower and an opposite end disposed to discharge air into the filter, the conveyor being shaped and arranged to obstruct all rectilinear paths between the blower and the opposite end.Type: GrantFiled: January 14, 2000Date of Patent: March 26, 2002Assignee: Honeywell International Inc.Inventors: Duane L.
