ROBUST BACKFLUSHER.

FOR CLEAN MELT.
 

Robustness, high level of automation and highest possible availability. Available in different sizes and always with the right filtration fineness With these EREMA filtration systems it is the details that make the system really effective.

The way SW RTF® technology works is to clean a small surface area of the filter screen by directing a flow of clean melt from the back of the screen. A high velocity is possible at the screen due to the small surface area of screen to be flushed, resulting in optimum cleaning efficiency.
