Filling and installation

Filter Unit can be produced very quickly (about 6 minutes to produce a 2t net) at a minimum of labor and no need for heavy equipment. They are ready to use within a minimum of time. Filter Units can be filled at site or outside the worksite, be stacked, stored and transported. The installation equipment may be an excavator, telehandler or crane.

A Filter Unit Rockbag is produced by placing an empty net into the production frame and filling it with stones or rocks. The Rockbag net is then drawn together at the top and the 6 hanging ropes are bound onto the single hanging ring. The production frame is lifted away and the Rockbag is now ready to be deployed. By reducing the amount of filling material the height and weight is adjustable. Filter Units are highly maneuverable due to the single point lifting system which allows for a quick, easy and safe installation or removal. Even after removal, Filter Units can be reutilized in a different application.
