An overhead vacuum assembly for recovering, storing and dispensing flowable packaging material including a flexible storage bag having an open upper end for receiving flowable packaging material, a dispensing valve mounted at the lower end of the bag, a liner or frame for maintaining the perimeter shape of the flexible bag, a cover mounted at the open upper end of the flexible bag, a fan motor assembly, including a filter, mounted to the cover for creating a vacuum in the bag and a hose mounted to the cover. The filter acts as a deflector to evenly distribute the loose fill throughout the bag during the recovery process. The cover may have a pyramidal shape and tear-away panels for ease of maintenance.
