Abstract: An air filtration system includes a frame directing an airflow through the air filtration system and a media filter. The media filter includes a plurality of media fibers arranged to capture particles flowing therethrough and a conductive surface located at the media filter and having a conductivity within a selected range. Two or more contact pads are located at the media filter and are alignable with an electrical circuit located at the frame to determine whether a resistance across the conductive plane is within a selected resistance range. A method of installing a media filter in an air filtration system includes inserting the media filter into a frame of the air filtration system and aligning one or more contact pads of the media filter with one or more grounding pads of the frame. A resistance across the media filter is measured.

Abstract: An onsite chemistry air filtration system to remove gaseous contaminants from air is disclosed. The onsite chemistry air filtration system of the present invention comprises: a conventional particulate filtration section, a photochemical filtration section, a static gas phase filtration section and a catalytic filtration section. The conventional particulate filtration section captures solids and condensables. In the photochemical filtration section, UV lamps generate bio-destruction and surface photochemical activity on a semiconductor catalyst material, provide a radiation source to irradiate airborne contaminant molecules and to energize their states to promote reactions and generate airborne ozone and radicals. In the static gas phase filtration section, gas phase filtration media is used to capture contaminants, concentrate them in a relatively confined space and allow airborne generated chemistries to concentrate and react in-situ, thereby creating a regeneration effect on the media. In the catalytic filtration section, catalytic media scavenges and converts airborne radicals and ozone to harmless by-products.

CPC classification number: B03C3/72
Abstract: A door latch and safety arrangement for an electrostatic precipitator is comprised of a spring contact to engage at least one of the plates of one polarity to thereby connect those plates to a first grounded terminal of a high voltage power supply when the door is in place and the latch is in the locked position. A test button is arranged so that when it is momentarily depressed and while the latch is locked, the spring contact is also moved towards the plates that are connected to the second terminal of the power supply and charged with the other polarity to thus produce an audible spark indicating the charged condition of the plates. When the latch is moved to the unlocked position, switch means connected therewith de-energizes the power supply. Moving the latch to the unlocked position also moves the spring means to simultaneously connect together precipitator plates of opposite charges and thus short circuit the collector cell and eliminate any residual charge therein.
