In the early 1900s, Schwartz Manufacturing began producing specialized fabric buffing wheels for the budding aluminum industry in Wisconsin. In the 1920s, the product line was expanded into industrial filters constructed of engineered fabrics. In the late 1940s, we entered the growing dairy industry with the development of isotropic milk filters, a significant innovation over gauze discs and other common food industry filters. Harlan Schwartz realized that the dairy industry had its own special needs for filtration. By developing a material specifically for milk filtration, he created a fabric that is still a leader in dairy sanitation. Four generations of the Schwartz Family have proudly owned Schwartz Manufacturing. It is now operated by Alessandra Schwartz, who is using her knowledge, along with the talented staff, to help customers solve their filtering needs and problems.
