ABSTRACT:
An apparatus and method for cleaning air filter elements of the type used in heavy duty internal combustion engines. The apparatus includes a frame to support air filter elements in position for rotation, a blower for forcing air through the filter and the element in a direction opposite the direction of air and dust entering the housing during use of the filter, an agitator operatively associated with the frame for loosening dust which entered the housing during use of the filter, a suction for drawing air through the filter and the element in a direction opposite the direction of air and dust entering the housing during use of the filter, and a pair of rollers to drive the filter element for rotation. The method includes supporting the filter element in position for rotation, forcing air through the filter and the element in a direction opposite the direction of air and dust entering the housing during use of the filter, agitating the filter and the element for loosening dust which entered the housing during use of the filter, drawing air through the filter and the element in a direction opposite the direction of air and dust entering the housing during use of the filter, and driving the filter element for rotation. By utilizing these combinations of features, dust accumulated in the air filter element during use can highly effectively be removed for cleaning the filter with the method and apparatus.
