KCH Continuous Screen Changer

Advanced Melt Filtration Technology

Product Image

In plastics extrusion, having the right screen changer for your material’s filtration requirements can make the difference between profit and loss. Parkinson Technologies’ line of Key Filters products offers custom engineered solutions and turnkey services to meet melt filtration needs for most thermoplastic materials.

The new KCH joins the best features of the prior KC and KCN product lines. The KCH delivers the same uniform continuous extrusion pressure, varying as little as ±20 psi. However, with hydraulic puller action, the KCH can react rapidly to disruptions caused by varying contaminant levels.

No process interruption translates into increased production and decreased scrap, bringing maximum efficiency to your extrusion operation.
