SMART CONTROLLER FOR REVERSE PULSE AIR FILTER

A control device for an air filter or dust collector equipped with a reverse pulse air cleaning system wherein the pressure differential across the air filter is continuously monitored and compared to a reference set point pressure differential. When the pressure differential across the air filter is greater than or equal to the reference set point pressure differential, a cleaning cycle is initiated. At the end of the cleaning cycle a new pressure differential across the air filter is measured and compared to the pressure differential before cleaning. If the new pressure differential is lower, it is stored and another cleaning cycle is initiated. This cycle is repeated until the "after" pressure differential is equal to or greater than the "pre-cleaning" pressure differential. At this point, a new reference set point pressure differential is calculated and the initial monitoring cycle is repeated until the pressure differential across the filter becomes equal to or greater than the new reference set point. The above described cleaning cycle is then repeated.
