Product features 

The automatic self-cleaning back-flushing filter is best-suited to continuous separation of solids such as sand from seawater. The robust construction and the automatic back-flushing contribute a great deal to operational safety and reduce operation and maintenance costs.

  • Back-flushing with its own medium, no external medium required
  • Flow rates up to 10,000 m3/h
  • Also available as a system solution combined with HYDAC heat exchanger 
  • Materials adapted to demanding offshore conditions
  • All control parameters can be monitored from a central operation control centre on the mainland 
  • Variable filter geometry (vertical / horizontal) 

Filter element technology

Reusable conical slotted tube or SuperMesh filter elements with filtration ratings from 25 to 3000 µm ensure effective separation of dirt particles in the filter. Our SuperFlush coating for filter elements is especially suited for use in seawater applications. It prevents the formation of biofilm as well as depositing and sticking of adhesive particles on the filter element surface.
