    Duperon® FlexRake® FPFS-M: Features & Benefits

    Low Maintenance

    With no lower sprocket, FlexRake® technology allows all maintenance to be done from the deck; no jam points underwater to require diving or confined space entry.

    Long-Life Durability

    Original FlexLinkTM multifunctional link system - with 4.5 lb. stainless steel cast links and an ultimate strength of 60,000 lbs. - provides unmatched durability.

    Adaptable to Variations in Debris

    Jam EvasionTM technology allows the FlexLinkTM multifunctional link system to lift and pivot around debris. This allows FlexRake® technology to adapt to a range of debris variations; positive FlexorTM-managed engagement assures continuous scraper capture.

    Energy Efficient

    The low horsepower requirements of the Sumitomo drive system ensures low-cost, energy-efficient debris removal.

    Efficient Hydrodynamics

    Depending on approach velocities, tear-shaped bars are 20% to 50% more efficient.

    High Capture Rate

    Unique in the industry, Thru-BarTM scrapers clean 3 sides of the bar as well as cross members.

    Cleans to Channel Bottom

    Eliminates residual debris buildup at the bottom of the screen; allows full use of channel depth for flow.
