Gusmer Enterprises Cellu-Flo Fiber Filter Aids

On pressure leaf filters, the basis for all good filter cakes is a sound precoat, and Gusmer has been manufacturing the filter precoat materials that are used in beer filtration for decades. Gusmer’s Cellu-Flo filter aids are widely used throughout the industry as a precoat because of their ability to form a fibrous matrix on the filter screens that provides a proper site for filter cake formation. This fibrous matrix also serves to protect the filter screens, virtually eliminates bleed-through, adds cake stability and allows for a quick and clean cake release at the end of the filter cycle. Cellu-Flo filter aids are available in many different fiber length distributions and formulations, including both cotton and wood pulp formulations, uncharged and charge modified formulations. Cellu-Flo RW and SL Series For Pressure Leaf Filters • Widely used for coarse and polish beer filtration applications as a precoat and bodyfeed adjunct • Derived from carefully selected softwood and hardwood cellulose and available in different fiber length distributions Cellu-Flo CLR and CLS Series For Pressure Leaf Filters • The best choice for ultrafine beer filtrations. Used as a precoat and bodyfeed adjunct • A must if preparing beer for subsequent sterile filtration • Derived from pure cotton linters cellulose and available in uncharged and charge modified (high zeta potential) versions and different fiber length distributions

Cellu-Flo fibers are available in bags and bulk pack totes. Contact your Gusmer representative for the optimal dosage rate and grade selection for your filtration application.
