Product Information
Depth Filter Sheets of the HS-Series

The HS series of Pall SeitzSchenk comprises
10 filter sheets with different retention rates.
The designation "HS" stands for high stability;
it characterises filter sheets with a very
pronounced rigidity which are suitable for use
at high temperatures as well as low temperatures.
The figure in the designation depicts
the degree of clarification of the filter sheet
and thus also its application possibility
whereby a small figure is synonymous with a
high degree of clarification.
Grades HS 200 and HS 400 are used for
sterilising filtration duties, whereas HS 600
and HS 800 are classified as micro-organism-reducing
depth filters. They can produce a
sterile filtrate at low organism counts in the
unfiltered product. The grades HS 1000
through to HS 9000 cover the entire range
from fine filtration via clarifying filtration to
coarse filtration.
The main components for the manufacture of
filter sheets of the HS-series are cellulose,
kieselguhr and perlite. A high specific output
combined with a long service life ensure an
economical operation, particularly in beer filtration.
A very high permanent wet strength
provides excellent behaviour during unloading
of the sheets after use.
