ABSTRACT:
This is a system for continuously cleaning warm-air furnace air filters by the reverse flow of air from the downstream, interior side of a portion of the filter to the upstream, exterior side of the filter which is rotating such that every portion of said filter is driven past the inlet of plenum or plenums at which locations reverse pressure generates reverse air flow to dislodge the dust and, thereby, clean and filter and to then drive the airborne duct into a fluid conduit which directs the collected dust into a combustion chamber, or into the exhaust vent pipe, or a dust receptacle. This assures a constantly clean filter, full air flow, and efficient heat transfer from heat exchanger into the occupied space requiring heat.
