Key Filters

Increase end-product quality and consistency, reduce scrap and achieve operating cost savings, especially when processing high recycled content polymers. For over 30 years, Key Filters melt filtration systems have provided worry-free contamination protection for compounding, pipe and profile, plastic film and sheet and specialty extrusion applications.

KCH Continuous Belt Screen Changer

Advanced Melt Filtration Technology

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 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.


Performance
  • Rapidly and automatically responds to increased contamination (pressure control) - true continuous system with little to no monitoring
  • Works with all thermoplastics and TPEs - tested on the most common material
  • Reliable Mechanical Puller Screen Advance – uniform and controlled screen movement
Innovation
  • ScreenLync™ interlocking continuous belt screen system - the first-of-its-kind interlocking system offers enhanced safety and efficiency
  • Quick Change Breaker Plate - Toolless removal of breaker plate in under 5 minutes.
  • Spent screen shear – device automatically cuts waste screen exiting the filter for easy disposal
  • Intuitive Controls - features built in U.S. & metric units of measurement along with language conversion (English, Spanish and Chinese)
Economical Solution
  • Low capital investment - quicker return on investment
  • Minimal operator involvement - labor savings and consistent product quality
  • Uses continuous belt of high tensile reverse Dutch weave filter media - low consumable screen cost

Savings Calculator

This calculator can be used to estimate the yearly potential production capacity (and resulting profits) that can be gained by upgrading from a discontinuous screen changer such as a manual, slide plate, or many times a dual bolt style screen changer, to a Continuous Belt Screen Changer. Upgrading is an easy way to increase production efficiency and profitability. Please contact us directly to discuss your application further.
