Fine filter BOXER KDX - To protect the residential water installation

The fine filters BOXER KDX are intended for the filtration of drinking water. The fine filter BOXER KDX with pressure reducer in addition is suitable for adjusting the outlet pressure on the withdrawal side. The fine filters BOXER KDX are designed according to the stipulations of DIN EN 13443-1 and DIN 19628 and are intended for installation into the drinking water pipes as per DIN EN 806-2 (installation immediately downstream of the water meter).
They protect water pipes and connected water-carrying system parts from  disturbances and corrosion damage due to undissolved impurities (particles) such as rust particles, sand, etc. The unfiltered drinking water flows into the filter from the inlet side and then from the outside in through the filter element and to the pure water outlet. Thus, foreign particles of > 100 μm in size are retained.
Depending on their size and weight, the foreign particles either stick to the filter element or they fall straight down into the filter cylinder.

  • All water contacting parts comply with the German Drinking Water Ordinance. Test regulations: KTW, DVGW W 270, DIN 50930-6.
  • The fine filter BOXER KDX features a flow-optimised pressure reducer with pressure gauge, integrated in the filter head, by which the outlet pressure on the outlet side can be adjusted and indicated.
  • All materials are recyclable.
