In 1977 Walter Herding established the Herding GmbH enterprise in Amberg/Germany. In the beginning it was cloth and needle felt filters which were produced for the mining and rock processing. However in 1978 the idea to create an alternative using sintered plastics was taking form and thus in 1981/1982 the Herding? sinter plate filter was born. This invention, the sinter plate filter element with patents all over the world revolutionized the status of the filter technology and formed the basis for the expansion and the success of Herding? Filtertechnik. Today Herding? Filtertechnik is a worldwide operating enterprise with currently 155 employees at its headquarters in Amberg/Germany and various affiliates all over Germany, companies in Belgium, the Czech Republic, in France, the Netherlands, Switzerland, Poland, the United States, China, and further co-operation partners worldwide.
