The automatic backwash filter BOXER A/AD offers the maximum comfort. The backwash process is released by timer-control. The backwash interval can be set between 7 and 90 days. However, the backwash process may also be released manually. The ergonomically shaped one-hand turning handle as well as the special backwash valve facilitate the release of the backwash even in case of high water pressure. Furthermore, the valve is designed in a way that it closes automatically.
