TROX provides an extensive filter product portfolio to offer its customers the optimum solution, both technically and economically. The portfolio includes filter units for different installation locations in walls, ductwork and ceilings, as well as filter elements for each requirement and each application situation.

The entire product range is manufactured in Germany, in the Goch production facility, and tested to comply with EN 779 or EN 1822, depending on the filter type. Testing to both standards is done in the Goch facility, on special test rigs that have been certified to ISO 9001. What is more, TROX M5 to F9 fine dust filters do not only comply with EN 779 but are also certified by EUROVENT.

For decades TROX experts have played a leading role in the development of national and international classification systems.
