A Vacuum Nutsch Filter (VNF) is a filtration device used to separate solids from liquids under vacuum conditions. It consists of a filter body, a filter media (usually cloth or mesh), and a vacuum system that enhances filtration by drawing the liquid through the media while retaining solids. VNFs are widely used in industries like chemicals, pharmaceuticals, and food processing, especially for filtering high-viscosity slurries, offering efficient separation with high purity.
