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.
