The chemical process industry makes extensive use of wire mesh filters. We manufacture our woven wire mesh in many high temperature and corrosion-resistant alloys to fit your application exactly. Our filter elements provide a large amount of open area while being highly porous, and Dorstener Drahtwerke can help you design wire mesh filters to optimize performance in your process. Many chemical process systems use wedge wire filters. We can engineer woven wire cloth filters to improve the performance of your OME wedge wire screen system.

We support you during development, planning, and engineering to get the right product for your application. In addition to standard products, we offer customized parts manufactured especially for you in a wide range of production depths. Therefore, call us at +49 2362 2099 0 or use our contact form!
