Employers are required to assess the risks posed by welding fumes and to implement appropriate protective measures. The Hazardous Substances Ordinance (GefStoffV) and the TRGS 528 require that welding fume emissions be captured as directly as possible at the source using state-of-the-art technology and that employee exposure be minimized.

Capturing fumes directly at the source prevents welding fumes from spreading throughout the production hall and being inhaled by employees. At the same time, it reduces the concentration of fumes in the hall’s air and increases the efficiency of the filtration system.

The right solution depends on various factors, such as the welding process, the number of workstations, the sizes of the components, and the manufacturing processes. Depending on the application, mobile welding fume filters, stationary fume filtration systems, or hall extraction systems are used.

A hall extraction system is particularly well-suited for large production areas or applications where it is not possible to capture all particulate matter directly at the source. It complements local exhaust ventilation and helps to permanently reduce fine particulate matter levels in the workshop air.

Our welding fume filters use high-performance filter cartridges that reliably capture fine dust and welding fumes. Various filter designs are available depending on the application and the materials used.

For applications involving recirculating air or when welding high-alloy materials, we offer optional HEPA H14 filters. With a filtration efficiency of 99.995% for particles at the Most Penetrating Particle Size (MPPS), they are suitable for the most demanding air filtration requirements. In addition, our systems can be equipped with activated carbon filters to effectively reduce gaseous emissions and odors.

Air recirculation is possible under certain conditions. In this context, the requirements of the Hazardous Substances Ordinance, TRGS 528, and the results of the risk assessment must be taken into account. The materials used, the filter technology, and the specific application are decisive factors.

The amount of fumes produced depends on the welding process and the materials used. In particular , MAG, MIG, manual arc, and flux-cored wire welding processes generate large amounts of welding fumes. TIG welding generally produces significantly fewer fumes.

Welding fumes consist of fine and ultrafine particles as well as gaseous emissions. Depending on the material and welding process, they may contain, among other things, metal oxides, manganese, nickel compounds, or chromium(VI) compounds.

Yes. Many existing workstations can be retrofitted with mobile or stationary welding fume extraction systems. The design is tailored to each individual setup based on the existing production conditions and workflows.
