Abstract
This is concerned with an air filter cleaning arrangement in which the filter element, meaning the pleated filter media and its frame, is functionally connected to a vibrator so that it is resiliently or vibrationally isolated from the surrounding structure. The major effective component of the vibratory motion applied to the filter media is across the width of the filter pleats. The invention is used primarily in an industrial sweeper. It can also be used in other machines or equipment which have air filter.
