Abstract: In a filter apparatus with a filter for filtering a liquid including, in a housing, a filter structure which is rotatably supported off-center so that it is arranged at one side in close proximity to the housing wall and at the opposite side a housing space is formed in which at least one nozzle tube with nozzle openings directed toward the filter structure and advantageously also an ultrasound transducer are arranged for removing deposits from the filter structure. A liquid inlet is connected to filter housing bottom wall in the area of the housing space and a return pipe is connected to the bottom wall in communication with a center passage of the filter structure for discharging cleaned liquid. The liquid inlet includes a valve for blocking the water flow and a drain opening for draining cleaning liquid during filter cleaning.

Abstract: In a pool filter with a filter for filtering the water of a pool including in a housing, a filter structure is rotatably supported off-center so that it is arranged at one side in close proximity to the housing wall and at the opposite side a housing space is formed in which at least one nozzle tube is arranged with nozzle openings directed toward the filter structure for washing off deposits from the filter. A pool water inlet is connected to filter housing bottom wall in the area of the housing space and a return pipe is connected to the bottom wall in communication with a center passage of the filter structure so that pool water can be circulated through the filter structure. The inlet pipe includes a valve for blocking the water flow and a drain opening for draining water during filter cleaning.
