The Duperon FlexRakeStandard Model is typically used for stormwater, pumpstation, hydroelectric, irrigation, or other applications where debris is varied and screen openings are coarse. Typical debris includes general refuse, aquatic vegetation, sticks, limbs, tires, and oil drums. The scrapers are usually serrated and configured to the barscreen. Ideal where continuous debris removal is necessary: no cycle times to allow for restricted waterflow.
The Duperon FlexRake® HD is used in open-channel applications (such as stormwater) where debris size, volume, and velocity may be unpredictable and where there are no upstream constraints such as influent pipes or pre-screening. Typical debris may include general refuse, aquatic vegetation, sticks, limbs, tires, and oil drums. Heavy duty scrapers are utilized to assist in high debris loadings.
