The Beam 110385 filter bag has been discontinued. The Beam 110379 Filter Bag is a near identical substitute.
This 110385 Beam filter bag is an 11" permanent, weighted, self-cleaning filter that fits a number of Beam Central vacuum models. 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.
This filter is can be used as a replacement for some models made in 2009 and earlier.
