Abstract
The present invention relates to a dust filter such as a hose filter which is mainly intended for cleaning primary gas containing dust or the like. The purpose of this invention is to simplify the cleaning process of the filter members and to reduce the design complexity for supplying pressurized gas thereto. To this end, the space above the cleaning gas nozzles is made in the shape of a pressure chamber, which reduces the need for the fittings and control devices.
