Abstract: A filter system including a filter housing with an inlet part, a clean-gas outlet, and a partition wall defining a product chamber and a clean-gas chamber. The partition wall having openings from which filter elements extend downward into the product chamber. The inlet part is placed in an upper part of the product chamber and configured for supplying a product-containing flow of gas to the product chamber. The gas flow being conveyed through the filter elements and into the clean-gas chamber, where the filter system is provided with an air or gas supply placed in the product chamber and configured for leading drying air or gas into or out of the filter system. A method of drying filter elements in a filter system by passing drying air or gas through a filter inlet and/or through a drying air or gas supply.

Abstract: A filter including a filter housing with a horizontal partition wall dividing the filter housing into a dean-gas chamber and a dust chamber. The filter has an inlet part in open communication with the dust chamber. The inlet part is configured for supplying a dust-containing flow of gas to the dust chamber. The gas flow is conveyed through the filter elements and upwards into the dean-gas chamber where the filtered gas is discharged through a clean-gas outlet. In the filter housing, a cylindrical inner portion is arranged that encircles the filter elements. A round-going inlet part is opposed to the cylindrical inner part. The round-going inlet part has a larger diameter than at least a portion of the filter housing that adjoins the inlet part. Gas flow is divided into an upwardly and downwardly oriented gas flow controlled by arrangement of the cylindrical inner part.

Abstract: The invention relates to a filter comprising a filter housing, an inlet and a cylindrical inner portion. The inlet is configured for conveying a gas flow into the filter whereby the gas flow is conveyed around a gap between filter housing and inner part, said inlet configured for supplying a particle-containing gas flow to the filter through the filter elements and out through a clean-gas outlet.

Abstract: The invention relates to a filter (1) comprising a filter housing (2), an inlet (13) and a cylindrical inner portion (14). The inlet (13) is configured for conveying a gas flow into the filter whereby the gas flow is conveyed around a gap between filter housing (2) and inner part (14), said inlet (13) being configured for supplying a particle-containing gas flow to the filter (1) through the filter elements (7) and out though a clean-gas outlet (9). In the filter housing (2) a cylindrical inner part (14) is arranged that encircles the filter elements (7) at least across a portion of the length of the filter elements (7) and that, on the filter housing (2) opposed to the area where the cylindrical inner portion (14) is arranged, a round-going inlet part (8) is configured, which inlet part (8) has a larger diameter than at least a part of the filter housing (2) that adjoins the inlet part (8).

Abstract: A filter for filtering a particle-containing medium and having nozzles includes a housing having an inlet opening and an outlet opening for the cleaning fluid, the openings forming between them a passage defined by a wall, a valve body having a valve head and a valve rod, the valve rod being arranged to be moved in the interior of the passage between a first end position and a second end position to control the flow of the cleaning fluid toward the partition plate and/or the filter devices, the outlet opening forming a valve seat adapted to cooperate with the valve head in the first position to prevent outflow of the cleaning fluid, and a spring for generating a bias of the valve body in a direction toward the first end position.
