Reliable filtration & protection

The Grünbeck fine filter BOXER KX

The BOXER KX fine filters are designed for the filtration of drinking water. The BOXER KX fine filters are designed according to the specifications of DIN EN 13443-1 and DIN 19628 and are intended for installation into the drinking water system according to DIN EN 806-2 (installation immediately downstream of the water meter system). They protect the water pipes and connected water-carrying system parts from disturbances and corrosion damage due to undissolved impurities (particles), such as rust particles, sand, etc.

BOXER KX fine filter to protect the domestic water system

The unfiltered drinking water flows into the filter from the inlet side and then from the outside in through the filter cartridge and to the pure water outlet. Thus, foreign particles with a size > 100 µm are retained. Depending on their size and weight, the foreign particles either stick to the filter cartridge, or they fall straight down into the filter cylinder. According to DIN EN 806-2, the filter cartridge must be replaced every 6 months at the latest.

By means of the flow-optimised pressure reducer of the BOXER KDX fine filter, which is designed according to DIN EN 1567, the outlet pressure on the withdrawal side can, in addition, be set to 1 – 6 bar (factory setting: 4 bar).
