Capture, clean, expel: how Ronningen-Petter systems from Eaton work
Every process is unique - that’s why we offer several backwashing/tubular systems in several configurations.

The simple, space-saving design of the AFR-Series - with only a single moving part - is ideal for the most demanding applications. The unit features a circular configuration of up to 8 tubes surrounding a central cleaning valve. During backwash, a diverter inside the cleaning valve rotates to the tube to be cleaned. This closes the tube to the incoming process liquid and opens it to the atmosphere (via the drain line). The result causes outlet process liquid to flow in reverse through the element, cleaning it of contaminants and expelling them through the drain.

AFR-Series - powerful performance in a compact footprint
The revolutionary Ronningen-Petter AFR-Series can replace an 8-station multiplex tubular system with a single unit in only a one-square-meter footprint. The simplicity of the AFR-Series design also helps to reduce overall system investment demands. Single systems can handle flow rates up to 2,000 gpm (454 m3/hr) and multiple units can be combined when higher flow rates are necessary.
