Fibroxcel products are chemically inert complex filter aids, which are used in the filtration of wine and alimentary liquids. They are used in the formation of precoats and/or coats and for the continuous dosing filtration for the filtration of wine, beer and products difficult to filter such as musts, lees, sugar syrups, etc. The high adsorbent power, which is the highest in Fibroxcel 30, enables to retain even very small particles such as yeasts, bacteria, coloring substances, proteins, ferric and ferrous ferrocyanide, etc.
