Product Description



FibraFix® depth filter sheets represent an approved and established filtration technology for solid liquid separation. The three dimensional medium assures superior retention capacity for solid particles at a high flow rate.

The pore sizes can be fine enough to retain bacteria and thus produce a sterile liquid (logarithmic retention of bacteria up to LrV 8).The dirt holding capacity of a FibraFix® depth filter sheet can be up to 4 kg per m2. in the filtration process, solid particles are slowed down and eventually retained by the tortuous path inside the filter sheet and by electrokinetical interactions («zeta potential»). Through this unique mechanism, a high capacity (long lifetime of filter until plugging) can be achieved.

All materials are food grade and FDA approved.


The broad variety of available porosities allow for their use in a wide range of applications. Porosity grades are available from coarse over fine to germ reducing and germ removing filtration («sterile filtra- tion»). Examples of industries:

– biotech
– beverage (beer, wine, spirits, juice…) – Cosmetics
– Enzymes
– Fine chemicals
– Herbal or other natural extracts
– inks, paints and glue
– Pharmaceutical intermediates
– Process water
– Solvents

Product range

The FIBRAFIX® range includes a support sheet and different grades of the standard series to choose from for coarse, clear or sterile depth filtration. They can be used in sheet or plate- and-frame filters such as the NOVOX® filter range (see technical data sheet). In addition, depth filter sheets are available built into lenticular modules (see technical data sheet for FILTRODISCTM modules and DISCSTARTM housings). FIBRAFIX® formats are obtainable in a range of 6 cm round sheets to 2.425 m × 1.215 m sheets, which allows application in any commercially available filter.
