, and Stor-Vac central vacuums will perform better and have longer motor life.
These bags fit vacuums over 34 inches tall (total length) and replace older #721-5 bags. Bag has an elastic top and comes five to a pack. On Air Force, Silent Master, Air Flo, and MD the bag fits over blue cloth support #711. Although this bag may seem big, it was designed this way. Our bag has more area to filter air. After inserting the bag open it up inside the vacuum by pushing down and out around the sides.
