- inventive use of a filter bag made of flexible material no cross-sectional extensions for the use of the filter element are required because the required filter area is significantly achieved over the length of the filter bag in the longitudinal direction of the filter tube. In this way, endless pipe systems can be produced inexpensively without large cross-sectional jumps, with high production speeds can be achieved while maintaining quality.
- the attachment of the filter bag is advantageous by clamping its circulating in the region of the bag opening edge between two adjacent pipe parts.
- no shapes for receiving fasteners must be provided on the inner wall of the filter pipe, since the already for mutual Attachment provided end portions of the tubes are used for clamping the filter bag.
- the flexible filter bag is a sectionally design of the tubular body as a bellows with creases particularly advantageous, wherein the tubular body is bendable by the bellows in these sections with respect to its longitudinal direction and the bellows adapts to any change in direction.
- Filter performance can be effectively increased in a small space, since the filter bags with their filter bottoms extend through the openings of the next filter bag and partially run inside the following filter bag.
- filter bags with different pore structure can be connected in a simple manner one behind the other, for example as a coarse separator and subsequent fine filter.
- the filter bags are arranged spaced apart in the longitudinal direction of the filter tube, resulting in spaces between the filter layers for receiving the previously filtered air.
- a simple and thus quick and inexpensive installation is given by attaching the filter bags to a mounting part, wherein the mounting part is used with the attached filter bags in the pipeline.
- the mounting part is itself formed as a tube and is connected to the respective adjoining end portions of tubular bodies. In this way, with a regular maintenance of the filter pipe, the mounting part with the filter bags exchanged in a few steps and new filter bags are used.
- the filter bag is preferably made of paper or non-woven.
