If you have an Electrolux (Beam) central vacuum that was built before January 2010 and you are having problems with loss of suction or the filter bag doesn’t seem to fit right make sure you’re using the correct filter bag for your system. According to Beam, systems that were built before January 2010 will use a different filter bag because of manufacturing differences with the new units. Here is the technical bulletin dated July 6, 2012.
Gore® 11″ “Shorty”
Filterbags – Service Part Notice
There was a slight increase in the cylinder expansion dimension
at the point of factory move from Webster City, USA to Juarez,
Mexico. With the slightly increased expansion, a similarly increased
filter-ring dimension (1/16″ increased band length ) became necessary
and this bigger ring became the standard for current production
Models and service filters. While the fit is ideal for current (2010
Onward) production, the bags are sometimes too big for pre-2010
Introduction of the second service filter bag variant (11 0380), with a
1/16″ shorter metal band cut length, provides ideal sealing in pre-2010
units. Part number 11 0347 is still to be used in many post-2010 units.
Note: Filter pull-tab seam should always be positioned on the foam
Tape for optimal seal.
