BOXER® KD – fine filter with pressure reducer

The manually operated, easy-to-replace fine filter BOXER® KD protects domestic water installations in accordance with DIN EN 806-2. Compared to the BOXER® K, it has a continuously adjustable pressure reducer (noise-tested). An integrated pressure gauge controls the water pressure. Otherwise, the BOXER® KD offers all the advantages of the BOXER® K. The filter body is made of easy-to-clean, high-grade technical plastic. The 12-part date indicator reminds you to replace the filter (DIN EN 806-5). The rotatable connection flange enables installation in horizontal or vertical pipes. The basic equipment of the BOXER® KD includes an 80 µm filter element (50 µm, 20 µm and 5 µm are optionally available). Fast conversion to a backwash filter BOXER® RD or automatic filter BOXER® AD is possible.
