Intended use

The filters are intended for filtering drinking and
domestic water. They protect water pipes and any
connected system parts for transporting water
from malfunctioning and against corrosion damage
caused by foreign particles such as rust, chip, sand,
and hemp, ...
The filters are not intended for use with chemically
treated circulating water. Seek specialist advice
when using the filters to filter process water and
cooling water for continuous cooling systems.
A coarse sediment bowl should be added for water
containing coarse sediment particles.
The filters are not suitable for oil, fat, solvents, soap,
and other lubricating media, nor for separating
water-soluble substances.

Function

Untreated water flows through the untreated water
inlet into the filter and there from the inside through
the filter element to the clean water outlet. Impuri-
ties > 90 µm are trapped on the inside of the filter
cloth. Depending on their weight and size of these
particles, these particles either fall directly onto
the lower section of the filter element or cling to
the filter cloth. The filter element can be cleaned
by backwashing at regular intervals.
Backwashing is carried out automatically after
a preset time interval according to the effective
principle of backwashing by suction (suction-ring
backwashing system).
The filtering process continues uninterrupted even
during the backwashing as 90 % of the filter sur-
face is constantly available for filtering (nonstop
filtration).
Infinity AP only
The pressure difference between the untreated
water inlet and the treated water outlet of the filter
is measured.
The backwashing process is triggered primarily by
differential pressure.
If heavy soiling of the filter element causes the
pressure difference to exceed the preset value
(approx. 0.8 bar) within the preset backwash inter-
val, the differential pressure generator causes the
unit to backwash. The preset backwash interval
starts again.
The filter is equipped with a central instrumentation
and control (CIC) connection (contact opens in the
event of malfunction or power failure).
