Duperon Tear-Shaped Bars Increase Screening Efficiency Up to 50%

Saginaw, MI – The custom tear-shaped bars employed on the Duperon® FlexRake® FPFS – a fine screen with Thru-Bar™ cleaning – provide up to a 50 percent screening efficiency advantage over rectangular- and circular-shaped bars (based on .25 inch bar openings). This efficiency advantage delivers dynamically improved flow characteristics, reduced slot velocity and less headloss.

The tear-shaped design keeps large debris on the surface of the screen, where it is easily removed by staging scrapers, while allowing debris smaller than .25 inch to flow through with optimum efficiency. In addition, Duperon® FlexRake® FPFS Thru-Bar™ scrapers clean three sides of the bar, as well as the horizontal cross members.

Duperon is the leader in preliminary liquids/solids separation technologies and provides technologies for coarse screening, fine screening, low flow screening, ultra screening, washing compacting, and conveying. Duperon technologies are designed, engineered, and manufactured in Saginaw, Michigan.
