This Beam 110361 Filter bag has been discontinued. The Beam 110346 Filter Bag is the appropriate substitute.
The 110361 filter bag is a permanent, weighted, self-cleaning filter for several Beam and Electrolux central vacuum units. When vacuuming, the bag with the weight inside it is sucked into the central vacuum unit's main canister. When the power is turned off, the filter falls and shakes off the debris.
