Perlite Filter Aide Food Grade for Filtration

Food Grade Perlite Filter Aide with a specific particle size to aid filtration. Used as a pre-coat over filter paper or in filter presses, and during winterization so fat crystals have more surfaces to form onto.

This is expanded silica with a high concentration of alumina with specific properties that make it ideal for removing fats and waxes on a rough pass (1st pass) filtration.  This special filter aide will help retain particles that are +50 microns.  It also retains little solvent to reduce losses.
