ABSTRACT:
The invention relates to a device for filtering a fluid, especially a liquefied plastic, said device comprising a housing, a supply channel, a discharge channel and optionally backwash channels. At least two filter elements are arranged in corresponding filter regions in the flow path of the fluid, in a filter carrier which is mounted in such a way that in can be perpendicularly displaced in relation to the direction of flow, said filter elements being able to communication with the supply channel and the discharge channel. Each filter region comprises two supply partial channels which are worked in to the filter carrier or the housing and are oriented away from the filter regions towards the discharge channel. Said discharge channel comprises housing partial channels which flow together to form the discharge channel. The supply channels can communication with the housing partial channels by displacing the filter carrier in such a way as to guide the fluid, and optionally the filter regions can be connected to the backflow channels by displacing the filter carrier.
