Designed for plants with 1 MGD or less average flow, the Duperon® FlexRake® Low Flow is pre-engineered to save you time and money.

Low FLow

Duperon® FlexRake® Low Flow Screen

  • No Lower Sprockets, Bearings, or Tracks to Foul or Jam

  • Adapts to a Range of Debris Variations

  • Tear-Shaped Bars are 20% to 50% More Efficient

    Duperon® FlexRake® Low Flow

    A front-clean, front-return, mechanically cleaned bar screen technology

    Specifically designed for plants of 1 MGD or less average flow with channels 2 feet to 6 feet deep by 1 foot to 2 feet wide.

    Bar openings of 1/4 inch, 1/2 inch, 3/4 inch, and 1 inch are available

    Duperon® FlexRake® Low Flow Features and Benefits

    Low Maintenance

    With no lower sprocket, FlexRake® technology allows all maintenance to be performed from the deck; no jam points underwater to require diving or confined space entry. No scheduled lubrication or maintenance is necessary.

    Pre-Engineered

    Integral enclosure, spray bar, and all stainless steel construction. Simple control system available.

    UHMW Low Flow SmartLink™ Technology

    The corrosion-resistant multifunctional links provide long operation life and permit "dry" operation.

    Energy Efficient

    The low horsepower requirements of the Sumitomo drive ensure a low-cost, energy-efficient method of debris removal.

    Efficient Hydrodynamics

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