BOXER® R – the flexible backwash filter

The manually operated and therefore easy-to-replace backwash filter BOXER® R protects domestic water installations in accordance with DIN EN 806-2. The flow-optimised filter is made of high-strength, high-grade technical plastic. The integrated 12-part date indicator reminds you to backwash (DIN EN 806-5). The ergonomically shaped one-hand turning handle as well as the special self-closing, low-water-hammer backwash valve facilitate the backwash release, even in the case of high water pressure. The filter fabric is made of stainless steel with a filter fineness of 100 µm. The BOXER® R can be connected to a drain pipe and be installed in horizontal or vertical pipes. Fast conversion to a fine filter BOXER® K or automatic filter BOXER® A is possible.

Please note local installation directives, general guidelines and technical specifications. The installation site must be frost-proof and the filter protected against chemicals, dyes, solvents, vapours and direct sunlight.
