ABSTRACT:
A filter arrangement that imposes an electric charge of "like" polarity upon particulate matter carried by a gas stream and upon a porous support for a filter whereby the particulate matter is repelled from the filter support but caused to collect loosely on the leading edge of the adjacent filter to form a loose bed of increasing thickness that enhances the effectiveness of the filter. The filter and the support therefor are both comprised of temperature resistant ceramic materials while a metallic coating on the surface of said ceramic support distributes the charge evenly to all portions of the filter support.
