Cleaner Filters. Longer Media Life. Lower Operating Costs.
Effective filter cleaning is critical to maintaining performance and extending media life. Roberts Filter Group offers a complete portfolio of auxiliary wash systems — including

Our Auxiliary Wash Solutions
Aries® Managed Air System
The industry standard in air scour technology, Aries® delivers controlled bursts of air during backwash to lift and agitate filter media. This reduces water use, enhances solids removal, and extends the life of the media bed.
Air Grid Systems
Roberts designs air distribution grids that evenly deliver scour air across the filter floor. These grids prevent dead zones, improve cleaning uniformity, and can be integrated with existing underdrain or retrofit projects.
Unisweep® Surface Wash Sweeps
Rotating surface wash sweeps provide additional agitation at the top of the media bed, breaking up crusts and dislodging fines that can accumulate between backwashes. Unisweep® ensures thorough cleaning from top to bottom.
