The invention relates to a vacuum-ceaning apparatus comprising a vacuum cleaner and a filter bag made of non-woven fabric, wherein the vacuum cleaner has a nominal electric input power of less than 1200 W, preferably less than 1100 W, more preferably less than 900 W, wherein the vacuum cleaner comprises a motor-fan unit and a controlling device controlling the vacuum cleaner such that the airflow is kept substantially constant at a value of at least 34 l/s, preferably substantially constant at a value of at least 37 l/s, more preferably substantially constant at a value of at least 40 l/s when the filter bag is loaded with DMT8 test dust analogous to EN 60312, and wherein the filter bag is a disposable filter bag made of non-woven fabric which has an airflow drop of less than 15%, preferably less than 10%, more preferably less than 5% in tests demonstrating the reduction of the maximum airflow with a partially filled dust container analogous to EN 60312.
摘要:
A flat bag for vacuum cleaners includes, in the interior thereof, at least two diffusers made of strips of material and/or sheet materials with oblong-shaped flow openings. Such flat bags are distinguished by excellent dust storage capacity and extension of the useful life.
摘要:
The invention relates to a vacuum cleaner filter bag comprising a first bag wall (104) comprising a filter material and a second bag wall also comprising a filter material and a base (103). The first and the second bag wall are joined to the base along one part of the periphery thereof and are joined together along the remaining part of the periphery. The connection between the first bag wall, the second bag wall and the base is formed such that the vacuum cleaner filter bag is completely closed. The filter material of the first and the second bag walls is made of non-woven material. Said vacuum cleaner filter bag comprises an opening (102) through which the air which is to be filtered can pass through into the vacuum cleaner filter bag, and a retaining plate. Said vacuum cleaner filter bag is characterised in that the first and/or the second bag wall comprises at least five folds (101).
摘要:
A flat bag is for vacuum cleaners. The bad includes, in the interior thereof, at least one diffuser which forms an intermediate plane and is made of strips of material and/or sheet materials with oblong-shaped flow openings. Such flat bags are distinguished by excellent dust storage capacity and extension of the useful life.

摘要:
A vacuum cleaner filter bag with an inlet opening and a deflection device arranged in the area of the inlet opening, which is configured in such a way that an air stream flowing through the inlet opening can be deflected.
摘要:
The invention relates to a vacuum cleaner filter bag having a composite material comprising a first layer consisting of a netting or a perforated sheet with an air permeability of at least 10,000 l/(m2 s), and a first fibre layer consisting of man-made fibres and/or vegetable fibres and connected to one side of the first layer.
摘要:
Described is a vacuum-cleaner bag which is made of an air-permeable filter material and forms a closed dust-collecting chamber, the vacuum-cleaner bag containing a material which can be whirled up under a given air flow.
摘要:
The invention relates to a vacuum cleaning apparatus comprising a vacuum cleaner and a filter bag. When using an empty filter bag, said vacuum cleaning apparatus has a quality factor QWun (defined as QWun=(hsaugun/hfbarun)×ψ where hsaugun is the vacuum, in [kPa], according to EN 60312, of the vacuum cleaning apparatus with an empty filter bag, hfbarun is the vacuum, in [kPa], in the filter bag-holding compartment with an empty filter bag, and ψ is the filtration efficiency, in [%], of the filter bag material) of more than 25, preferably more than 30, and/or when using a partly filled filter bag, the vacuum cleaning apparatus has a quality factor QWteil (defined as QWteil=(hsaugteil/hfbarteil)×ψ where hsaugteil is the vacuum, in [kPa], according to EN 60312, of the vacuum cleaning apparatus with a partly filled filter bag, hfbarteil is the vacuum, in [kPa], in the filter bag-holding compartment with a partly filled filter bag, and ψ is the filtration efficiency, in [%], of the filter bag material of more than 13, preferably more than 15, especially preferably more than 17.
