We assemble our filter systems ourselves

The installation is carried out by our own trained service team since it is of great importance to assemble everything right. In that way later problems can be avoided. Especially when it comes to plants with explosion protection etc., it is important for us to personally assure our customers that everything works as it should. This corresponds to our understanding of quality.
