A special feature of this design is the submersible screen grid which is scraped by several circulating screen rakes. The number of scraper rakes and thus the scraping velocity are variable - thereby guaranteeing also highload scraping. One decisive advantage of the submersible screen grid is that there is no necessity for a separate bypass channel or system.
Furthermore a Counterflow Screen allows to replace and automatise cleaning of manually scraped screen girds in existing emergency bypass channels.

- Bars on screen combs can be replaced individually
- The number of scraper bars and thus the scraping intervals are variable and can be adjusted to suit prevailing circumstances
- No emergency bypass required, as the screen grid is floodable
- Operationally reliable and robust
- Parts which are in contact with waste water are made from stainless steel
- Maintenance-free bearings
- Automation upon request
- Maintenance-free drive unit with geared motor
- Easily accessible chain tensioning devices
- Long service life thanks to well-built, robust engineering and design
- All movable parts come after the screen grid
- Explosion-protected
