KNOCKS FLUID Technik
From the basement to the worldThe German company KNOCKS FLUID Technik was founded as a family business in 1970. The company, which in its early days was run by its founder in the basement of his house, has grown into one of the leaders in the compressed air industry in less than 50 years. But the company continues to keep pace, and year after year its ranks have grown, while the development of new technologies has not been overlooked. But it wasn't just the desire for expansion, but also the desire for excellence that kept the company going. In 2004, the certification according to ISO 9001: 2000 came quite logically. The complete production of the entire product range is carried out at the company's headquarters in Selm, where, for example, proportional regulators, various types of couplings, pressure regulators, as well as silent blocks are produced. |
