Abstract
A filter including a filter housing with an essentially horizontal partition wall that divides the filter housing into a clean-air chamber and a dust chamber. The partition wall is provided with a number of apertures in which a number of filter bags are provided that are secured to the partition wall and extend down into the dust chamber. The filter is provided with an inlet portion in open communication with the dust chamber in a level that is above a lowermost end of the filter bags, wherein the inlet portion is configured for introducing a dust-containing flow of air into the dust chamber, from there it can be sucked through the filter bags and up into the clean-air chamber, from where the filtered air is discharged through a clean air outlet. A number of diffuser elements are arranged in the inlet portion outside the filter housing.
