New back-flush filter for film extrusion for use with regranulate

The cutting edge ultra-compact high performance filter from MAAG Group comes along with large static conical screen area, through which the melt flows from the inside to the outside. An axial aligned moving flushing piston is permanently cleaning sections of contaminated screen area. The contaminated share of material is directly guided outward. Beneficially feature of this new design: The convex room is completely dead space free and fl ow optimized which doesn’t allow any stagnation of material – outcome of this is low residence time. Already purified melt neither get harmed by any moving or blocking parts nor do rotating parts have impact on melt quality. On the basis of continuous and high effective backflush of the whole screen area the pressure deviation in the system remains steady over a very long time.
