Filter Device

A filter device, comprising at least:

• a filter, which is divided into individual segments;
• a cleaning device, which has, associated with each filter segment, a partial cleaning unit, which can be moved along the cleaning device and which cooperates with a rotatable discharge device with individual discharge openings which, brought into at least partial alignment with passage points in the cleaning device, serves to discharge a fluid flow from the filter;
• and
• a control device, which activates at least one partial cleaning unit for cleaning, whereas at least one further partial cleaning unit remains inactive during this cleaning;
• wherein
• the control device has a coupling device, which, in one position of the coupling device, connects the cleaning device to the discharge device for a common rotary movement and, in another position of the coupling device, disconnects them from each other.
