The maintenance-friendly Helisieve M in-channel fine screen employs a shaft-less spiral to perform screening, solids conveying and dewatering in one cost-efficient operation. At the heart of the system is a heavy-duty, carbon steel spiral that conveys screenings to the dewatering zone and prepares them to acceptable landfill requirements. Screen angles are now available in 35 and 45 degrees. A segmented brush design reduces replacement time by at least 25%. The new wear bar design increases wear life by 30%. The system features a top-mounted hinged cover for easy press zone access.
