Abstract : This invention relates to a reversed air system for periodically cleaning one or more filter panels of an engine air cleaner. The cleaner system includes an air nozzle at one face of the filter panel and an air receiver at the other panel face. The nozzle and receiver are arranged on ball screws for transverse movement across the filter panel faces. Under our invention, the air receiver has flexible connections with ball nuts that travel along the associated ball screws. The flexible connections have swing flexibility in different planes to alleviate potential jamming tendencies due to manufacturing tolerances, installation variances, and ball screw sag due to the unsupported length of each screw.
