Reliable filtration & protection

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. The unfiltered drinking water flows through the inlet side into the filter and then passes from the outside towards the inside through the filter element to the pure water outlet. Thus, foreign particles with a size > 100 µm are retained. Depending on their size and weight, foreign particles stick to the filter element or they fall straight down into the filter cylinder.

The drain is opened by turning the backwash handwheel as far as it will go, and backwashing is carried out. The water flows through the primary screen to the filter element and then passes through the filter element in the opposite direction to normal filtration. Particles sticking to the filter element are detached and washed out to the drain.

We recommend performing a backwash every two months. In the case of the backwash filter BOXER RDX with pressure reducer, the flow-optimised pressure reducer, which is designed according to DIN EN 1567, enables the holding pressure on the withdrawal side to be set to 1 – 6 bar (factory setting: 4 bar).

• Connection flange incl. water meter screw connections (made of dezincification-resistant brass) with seals and stainless steel screws
• Filter element made of stainless steel mesh
• Maintenance ring for setting the next maintenance date (backwash).
• Ergonomic handwheel for easier release of backwash
• Transparent blue filter cylinder that can be tightened by hand
• Drain connection DN 50 according to DIN EN 1717 for connection to the drain pipe with integrated outlet.
• In order to set and indicate the after-pressure on the outlet side, a pressure reducer with pressure gauge is integrated in the filter head of the BOXER RDX.
• All water contacting parts comply with the German Drinking Water Ordinance. Test regulations: KTW, DVGW W 270, DIN 50930-6
• Recyclable materials
