Definitions

  • filter bags for vacuum cleaners which have an interior for receiving dust, and may be formed as a flat or block bottom bag.
  • a filter material paper or a nonwoven fabric is used, with multi-layer filter materials are used for effective filtering. This dust particles can settle with increasing filling just in a fine filtration in the outer region of the bag, resulting in a blockage. As the filling increases, therefore, the air volume flow conveyed through the filter bag decreases.
  • a first chamber for coarse filtering of the incoming air and a second chamber for fine filtering of the air exiting from the first chamber is used.
  • larger dust particles can be prefiltered and they can not clog the pores of the fine filter.
  • FIGS. 2A to 2C is a second embodiment of a filter bag 1 'shown, in which the layers 2 and 3 are formed of filter material and the holding plate 5 with the inflow opening 6 as in the first embodiment.
  • the subdivision of the interior of the bag into a first chamber 9 'and a second chamber 10' does not take place via a bag-shaped dividing wall but through a dividing wall 7 'which is fixed on opposite sides to the layers 2 and 3.
