Our innovative design and development team works quickly and accurately thanks to their excellent know-how. Thanks to the pooling of all specialist expertise at our site in Selm, we not only offer short communication channels to you, but also efficient internal coordination between our departments.

With the help of internal investigations in our in-house development center, we can determine your specifications to the point and arrive at an optimal solution. In addition, our in-house rapid prototyping enables us to provide sample devices (3D-printed) promptly to assess sizes and handling.

From development
to series production.

From development
to series production.

All new products, including custom-made applications that we have developed at the customer's request, undergo a series of validation tests before they are ready for series production, which put the new product through its paces. At the same time, we check whether the item meets the required specifications. Only after successful final acceptance the product goes into series production. The tests for new products include service life tests, endurance tests, burst pressure tests, temperature resistance tests and leakage tests. In addition, tests and inspections are carried out during series production to ensure the top quality of all KNOCKS products.

Our employees use automated test benches to check every product and our thorough quality management system ensures that only flawless devices leave our premises. We manufacture a large number of product variants that differ in terms of special production variants and details as well as their possible combinations. Combined into larger assemblies or even pre-assembled for you as a system solution, the result is always a top product that is ready for connection.

In mechanical engineering, medical technology and many other industries, compressed air regulators, filters and lubricators are important components of an entire machine that are of increasing importance and must function reliably. You can rely on us and benefit from our pre-assembled FRL solutions. These are manufactured exactly to your specifications and assembled ready for connection. This reduces the number of parts you need, lowers storage costs and saves assembly costs.

Top quality is our priority! This is not only demonstrated by our ISO 9001:2015 certification, but also by the fact that all of our products undergo a series of different tests and quality checks that guarantee 100% product quality. A special high-pressure test bench for pressures up to 60 bar and a large number of automated series test benches are located directly in production. Various sampling and approval procedures, special tests and laboratory tests round off the comprehensive tests.
