Abstract
An endless filtering sheet, having an interior entrained about rollers, extends in a path of movement over an air inlet in a housing for receiving air flow and presents an exterior from which dirt and debris collected from the incoming air flow and which dirt and debris is removed in a horizontal reach by gravity and/or an air flow. A drive mechanism continuously moves the sheet in the endless path to provide a continuously operating air filtration system for a heat exchanger in a HVAC system that is self-cleaning.
