The invention relates to a dust filter comprising a vertically arranged filter housing (1) and a partition (2) which separates the filter housing (1) into a lower dust contaminated air chamber (3) and an upper clean air chamber (4). Said partition comprises many openings in which self-supporting filter tubes (5) are hung, which are open to the clean air chamber (4) at the top, and means (10, 16) are provided to clean off the dust and product particles adhering to the outer surface of said filter tubes (5). Where headroom is limited, the dust filter can be made easier to clean by collecting several filter tubes (5) in a filter bundle (7), whereby the separation between filter tubes (5) in each filter bundle (7) is less than the separation between individual filter bundles(7). |
