ABSTRACT:
There is provided a fluid filter system cleanable by suction. The system comprises a filter element fixedly attached to a substantially rigid filter-element support mounted in a filter housing and provided with a plurality of openings, at least one suction nozzle having an inlet opening located in close proximity to the filter element and adapted to move with its inlet opening past the filter element in such a way as to cover, in succession, at least some zones of the filter element while producing a suction flow. The invention further comprises guide means for guiding a fluid stream from the high-pressure raw-fluid space of the filter housing to a low-pressure zone created by the suction nozzle between the inlet opening thereof and that portion of the filter-element support which faces the suction nozzle.
