Pall Corp HS-Series Filter Sheets
The main components of the Pall HS-series filter sheets are cellulose, kiesselguhr and perlite. A high
specific output combined with a long service life ensure an economical operation, particularly in beer
filtration. Grade HS 400 is used for sterilizing filtration, whereas grade HS 1600, HS 2000 and HS 4000
cover the entire range from fine filtration via clarifying to coarse filtration.

Diatomaceous Earth (DE)
The most popular filtration powder used by brewers is diatomaceous earth (DE), which consists of
skeletal remains of single-celled plants called "diatoms" that contain silicon dioxide.
Silbrico Sil-Kleer (Perlite)
Silbrico Sil-Kleer is a unique filter aid made from volcanic rock which is expanded and milled to specific
grades. The resulting filter aid is an extremely pure, inert, white, light weight filter aid having a unique
interlocking structure with myriads of microscopic channels. It affords optimum flow rates and sparkling
clarity. When using Silbrico Sil-Kleer filter aid in place of other products, different operating procedures
may be required. Silbrico Sil-Kleer should be used on a volumetric basis (i.e.: bag for bag) because
Silbrico Sil-Kleer is considerably lighter than most other filter aid products. Standard grade from fine to
coarse include -
Eagle Cel (Cellulose)
Used in conjunction with DE as pre-coating for rough and polish filtration.
Rice Hulls
Add up to 10% rice hulls to enhance the filtration effectiveness of the lauter bed. Particularly beneficial
