Abstract
A filtration device and method for removing particulate matter entrained in a gas stream including a filter media with a first prescribed surface area on one side thereof; a perforated support for positioning the filter media so that one side thereof is in communication with the gas stream with the particulate matter entrained therein; a suction head defining a suction inlet therein with a second prescribed cross-sectional area smaller than the first prescribed surface area of the filter media on that side of said filter media opposite the side in communication with the gas stream; a fan for forcing the gas stream into the suction head through the filter media to separate the particulate matter from the gas stream; and drive means for moving the suction head along the filter media so that substantially all of the filter media is eventually used.
