  • Method for cleaning a dust filter
    Patent number: 3954426
    Abstract: For cleaning a dust filter having a filter element of flexible material forming at least partly a flow passage there is imparted to wave movement to the filter element and another wave movement to the fluid in the flow passage by means of fluid impulses supplied by an oscillation generating member substantially in the main direction of the flow passage. The wave movements are related and coupled to one another in such a way that the movement amplitude of the oscillation of the filter element and the pressure and speed amplitudes of the oscillation of the fluid will reach their peaks essentially simultaneously.
