A filtering apparatus has filtering elements () in a filter housing (), a filter inlet () and a filter outlet (). During filtration, one of the filter elements () can be back-flushed by a back-flushing device (), having a pressure control device (). The pressure control device has a hydraulic accumulator (), with a fluid chamber () fillable during filtration with clean fluid and connectable for back-flushing via a back-flushing guide () to the clean side () of the filtering element () to be cleaned. For back-flushing, a further fluid chamber () of the hydraulic accumulator () is subjected to gas pressure. By resultant movement of a separator () of the hydraulic accumulator (), the filling amount of the clean fluid is dispensed for the back-flushing.

Filtering apparatus

A filter device includes at least one filter housing () in which at least one filter element () is arranged. Inside the filter housing (), the filter element separates a clean side () from an untreated side (). On the clean side () of the filter housing () at least one storage unit () having at least one movable separating element () is connected. The separating element divides the storage unit () into two working chambers or pressure chambers () ().

Filter device

A separating device for separating a multiphase medium includes a cyclone separating device () that provokes an at least partial distribution of at least two phases of the medium with the formation of a vortex flow for the medium. Each phase having a lower density compared to the other phase is separated from the other phase and can be guided out of the separating device by a collecting device ().
