3 Product description
3.1 Intended use
●The fine filters BOXER KX and BOXER KDX are intended
for filtering drinking water and for installation into drinking
water pipes according to DIN EN 806-2 (installation
immediately downstream of the water meter).
●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 fine filter BOXER KDX with pressure reducer is
additionally suitable for adjusting the holding pressure on
the withdrawal side.
●The filters can be used for positive pressure and negative
pressure applications. The adjustment of the after-pressure
on the withdrawal side, however, only works when applied
in the positive pressure range.
3.2 Predictable misuse
●The filters are not suitable for circulation water that is
treated with chemicals.
●They are neither suitable for oils, greases, solvents, soaps
and other lubricating media, nor for the separation of water-
soluble substances.

3.4 Functional description
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 of > 100 µm in size 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.
In the fine filter BOXER KDX, 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).
3.5 Accessories/consumables
You can retrofit accessories to your product. Please contact
your local Grünbeck representative or Grünbeck's headquarters
in Hoechstaedt for details.
