  • a lint filter is typically used in a process air duct to retain fibers and other finely divided particles, collectively referred to as fluff, entrained by a laundry in a drying process so that they do not contain any functional units, such as blowers, in the process air duct, Pumps, heating, heat exchangers, waterways, airways etc. can contaminate or even clog.

  • the gauze is so far designed so that a free passage area of about 36% to 45% of the total area and a mesh size of 100 ⁇ to 200 ⁇ is guaranteed, otherwise the lint filter clogs too fast and its air resistance to passing through process air too high becomes. Finer gauze with a mesh size of less than 150 ⁇ tends to clog quickly during a drying process. This means, however, that hair in the process air, which have an average diameter between 40 ⁇ and 120 ⁇ (a mean diameter of hair is about 80 ⁇ ), pass through this gauze and in the downstream air ducts and components such as heating, heat exchangers , Blowers, etc. can arrive.
  • EP 2 072 660 A1 discloses a laundry drying apparatus having a lint filter connected upstream of a heat exchanger, which lint can be cleaned of lint by means of a corresponding purging device and makes the conventional manual removal of lint from the lint filter unnecessary following a drying process.
