As a manufacturer of filters, we have been one of the leading international names in the development, project planning, production, sales and assembly of filters and filtration systems for aqueous, viscous, highly viscous and pasty media for over 30 years. Our filter systems can be used to separate solids from liquids. We are an experienced and future-oriented filter specialist with in-depth expertise and a competent team of engineers and technicians.
