The Dual Flow screen is an outward-facing band screen. Flow enters the screening elements from the outside of the plates and flows to the center of the U-shaped screen belt where it is discharged. Screenings are carried to the top axis by the filter elements where they are conveyed to the screenings discharge. Large items like stones are lifted by steel fingers placed between every few sets of filter elements. 

Screen panels are made of stainless steel mesh for water intake applications or perforated plate for heavier load applications.  A special sealing configuration prevents carry over to the downstream side of the channel.  A spray bar positioned at the top axis of the screen belt provides the primary cleaning, with an optional brush available for heavy debris loading.
