A filter-cleaning apparatus utilizes pulsed air to remove matter collected on a first surface of a filter. Reverse flow loosens the material which is collected in a hopper on the upstream side of the filter. The collected matter may then be combusted in the hopper so that the amount of material collected is minimized. The pulses are directed at the filter with a controlled shape and time to optimize reverse pulsing. Pulsing occurs while the thermal exhaust flow continues so that operation of the engine is not interrupted. A number of valves may be utilized to clean one or more filters.

A method for cleaning at least two air filters, each filter having an associated horizontal duct portion, having air flow from above the filters and swept down, and through the filters in a substantially horizontal direction, comprising the steps of: (a) producing a reverse pulse of air on an outlet side of the filters during continued air flow; (b) directing the reverse pulse of air substantially horizontally onto the outlet side of two or more of the filters in a predetermined pattern; and (c) sweeping loosened debris from an inlet side of the filter downward to a plurality of horizontal duct portions, and down through a single vertical duct from the plurality of horizontal duct portions and collecting the loosened debris.
