The Discontinuous Screen Changer (DSC) provides convenient, easy access melt filtration for polymer and hot melt adhesive batch operations. The design features a single filter pocket machined into a cross-bolt. Shifted offline only for momentary screen change, the easy-to-clean filter pocket has no hang-up areas and features a streamlined flow channel for fast material or color changes without cross-contamination. The self-sealing design has no mechanical parts to wear out or replace. Maintenance is reduced to periodic cleaning of the cross-bolt.
An optional patented seal insert allows the Discontinuous Screen Changer to filter materials with viscosities as low as 10 centipoise / 1800 MFI without risk of leakage. The design can also accommodate an integral divert for batch operation startup or changeover.
