The AP screen changer delivers continuous, self-cleaning filtration for low to medium-contaminated materials — maintaining extreme melt pressure stability without stopping your extrusion line.
Protected by Cofit patent, AP filter cartridges get cleaned without being taken out of the block.
AP filtering cartridges can be cleaned and replaced without production interruption.
AP screen changer does not require any expensive control panel or hydraulic control units.
AP is optimized for low to medium contamination materials in film, sheet, fiber and most continuous applications where melt quality and uptime are critical.
