The filter media may further include a mixed fiber filter layer having fibers from different sides of the triboelectric scale. The filter media may further include a layer of relatively higher density dielectric material followed by a layer of relatively lower density dielectric material.

Abstract

An air cleaner for an enclosed electronic device such as an electronic slot machine, for use in areas that have a high level of air contamination from cigarette smoking such as casinos, includes an active field polarized media air cleaner or other fillers for removing sub- micron particles, tars and/or volatile organic compounds ( VOCs). Tn addition, a shared air cleaner for removing sub-micron particles, tars and/or VOCs is coupled Io a plurality of enclosed electronic devices, such as a cluster of electronic slot machines.

• B03C 3/04 - Plant or installations having external electricity supply dry type

Abstract

Improvements in active field polarized media air cleaner include an aerodynamic front cowling to reduce static air resistance, a rear double hinge to reduce blow by, a resistive center screen permitting the sharing of high voltage power supplies while reducing the tendency to arc and allowing for a higher operational voltage, a dielectric media support frame to produce a more uniform electrostatic field and reduce blow by, while at the same time reducing the tendency to spray corona and/or arc at the edges of the center screen, a substantially flat conductive outer screen to produce a more uniform electrostatic field throughout the filter media and a high-voltage shield to reduce high-voltage arcing and the spraying of corona where the high-voltage probe contacts the center screen.

IPC Classes  ?

• B03C 3/00 - Separating dispersed particles from gases or vapour, e.g. air, by electrostatic effect

• B03C 3/04 - Plant or installations having external electricity supply dry type

Abstract

A pleated filter media includes a plurality of parallel conductive beads to support the media and space the pleated surfaces apart. A high voltage differential applied between adjacent conductive beads induces an electrostatic field within the filter media, thereby increasing the efficiency of the filter.
