Abstract
A filter device, in particular, for high-pressure applications in a molten polymer filtration, has a screw-in piece (), provided with a first threaded section () for fixing the filter device, and a second threaded section () for fixing a filter medium (), in particular, in the form of a metal wool and with a perforated support tube () for the metal wool. The other free end of the filter device is provided with a volume displacer (). The metal wool is surrounded by a support grid () and fixed by two fixing pieces (), held at a separation from each other by the support grid (). One fixing piece () is fixed to the second threaded section () of the screw-in piece (). The other fixing piece forms a handle () for the fixing formed. As a result of the volume displacer () being a one-piece component of the support tube () and the fixing piece () forming the handle covering the volume displacer (), the filter device is significantly improved in that a simple and rapid assembly procedure for the exchangeable filter medium is provided. Also, the filter element construction is held formed to be free of damaging torsional loads.
