Publication number: 20200188929Abstract: An electrostatic air cleaner may include a corona charging stage, a precipitation stage, and an air mover (fan). The corona charging stage may include a first and second array placed under electrical potential difference capable of generating a corona discharge. The first array may be substantially parallel corona wires and may be located downstream of an air penetrable second array. The precipitation stage may be downstream from the corona charging stage. The spacing between the first array and the second array may be less than the distance of the precipitation stage to the second array. The air mover may be upstream of the corona charging stage or downstream of the precipitation stage or between these stages. The arrangement allows for higher ion output downstream of the first array with the same voltage and power consumption resulting in greater particle charging and better air cleaning efficiency.Type: ApplicationFiled: December 13, 2018Publication date: June 18, 2020Applicant: Pacific Air Filtration Holdings, LLCInventor: Igor Krichtafovitch

Publication number: 20200188931Abstract: An electrostatic device, for example, an electrostatic air cleaner, may be provided with a corona discharge electrode; a collecting electrode; a power source connected to the corona discharge electrode and to the collecting electrode; an electrical parameter sensor; and a power supply system. The control system may receive a signal from the electrical sensor. The control system evaluates the electrical performance of the system and initiates appropriate or corrective action.Type: ApplicationFiled: December 13, 2018Publication date: June 18, 2020Applicant: Pacific Air Filtration Holdings, LLCInventor: Igor Krichtafovitch

Publication number: 20200188932Abstract: An electrostatic air cleaner may be operated according to a manner designed to achieve acceptable air quality while balancing power usage and corona electrode degradation levels. The voltage applied to the corona electrode(s) may be controlled as well as the voltage applied to repelling electrodes and air flow velocity. The air cleaner may also be operated to achieve desired particle separation.Type: ApplicationFiled: December 13, 2018Publication date: June 18, 2020Applicant: Pacific Air Filtration Holdings, LLCInventor: Igor Krichtafovitch

Publication number: 20190351431Abstract: An electronic air filter having a plurality of electrodes supported by rigid fixtures that are attached to a common case. The rigid fixtures that support the electrodes with different electrical potentials are attached to each other or to a common body in a way that increases or maximizes the creeping discharge path along the surface. Even conductive contaminants do not, therefore, provide an electrical shortage between the electrodes.Type: ApplicationFiled: June 13, 2017Publication date: November 21, 2019Applicant: Pacific Air Filtration Holdings, LLCInventor: Igor Krichtafovitch

Publication number: 20190329269Abstract: A collecting electrode element for an electrostatic air cleaner with a reduced weight can be constructed with a lightweight conductive core sandwiched between particle collection layers which are supported and stabilized by a rigid frame. The conductive core may be conductive foil, conductive film, conductive ink, or conductive glue. The particle collecting layers may be flexible open-cell foam such as melamine which may be compressed between opposing frame elements. The frame may leave most and preferably at least 90% of the surface of the particle collecting layers exposed. The frame may have opposing frame elements secured to each other at a compressed area of the particle-collecting layers.Type: ApplicationFiled: June 13, 2017Publication date: October 31, 2019Applicant: Pacific Air Filtration Holdings, LLCInventor: Igor KRICHTAFOVITCH
