This company has equipped several plants for the production of blown film with continuous screen changers of the type K-SWE. The screen changers were equipped with a separate control to guarantee smooth and reliable filter change during operation. The retrofit should eliminate production-line shutdowns during filter change and improve filtration results, thereby increasing plant availability and productivity. The K-SWE screen changer enables the exchange of the mesh without interrupting production; conventional blown-film plants use discontinuous screen-changer systems that require the line to shut down for filter changes. — Kreyenborg GmbH, Münster, Germany
