Model RFR -Round-Finescreen

To be used for preliminary sewage treatment direct at pumped WWTP inlet or integrated in our compact unit or septic reception unit. Sturdy and reliable design in stainless steel. Installation width up to 1,50 m. Gap width between bars from 0.5 to 6 mm. Variation of gap width easily possible just by changing the grid within 15 minutes. Lowest possible maintenance costs. Proper scraping of screening goods beginning at the bottom and therefore no disturbing sedimentation in front of screen grid. Discharge of screening goods by double-arm-scraper in very short time intervals. Drive shaft of double-arm-scraper is automatically and self moving aside in case of potential blockings. Suits very well for highest hydraulic flows at small channel measurements, because bended grid surface is nearly double as big as the cross-section. Compact design and ideal suitability for replacements. Hygienically capsulated by easy removable covers. No bearings, drives, brushes or reverse devices below water level – which means wear and tear free scraping and no lubricating, adjusting or strengthening. Optional the integrated screenings washing press could be delivered with an easy replaceable hardened spiral top end; the screening system could furthermore be extended by our intensive washer or conveyor devices.
