Duperon Tear Shaped Bars Increase Screening Efficiency By Up To 50 Percent

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.
