WELDING FUME – WHAT ARE THE HEALTH CONCERNS AND HOW WELDING FUME COLLECTORS CAN HELP?
Welding fumes occur when metals are welded. But what exactly is welding fume? What health concerns prevail? How ESTA welding fume collectors can help provide a healthier work environment? Find the answers to those questions below.
Dust particles in welding fumes are partially smaller than 0.1 μm and therefore are able to enter the alveoli, which means they can advance to the pulmonary alveoli of the lungs when inhaled.
Due to the small size of the welding dust particles they are neither clearly visible nor directly noticeable. This makes the welding fumes even more dangerous as they deposit unnoticed in the body initially and then cause damages. Possible health concerns are dizziness, nausea, headaches, respiratory diseases, nerve damages and even cancer.
Because of those health concerns, welding fumes are categorized as hazardous substances according to the „Dangerous Goods Declaration“ called Gefahrenstoffverordnung (GefStoffV) in Germany.

Whether welding fumes have a rather burdensome impact on the respiratory system, are toxic or have cancerous effects depends on the occuring contaminants.
ESTA offers ventilation systems in order to effectively exhaustwelding fumes to protect the health of employees and adhere to legal requirements concerning welding fumes. To ensure optimal welding fume extraction individual circumstances such as type of work place (mobile or stationary), welding procedure or the composition of the work piece have to be taken into consideration.
Mobile welding fume filter
Welding fume filters for mobile installation are particularly flexible and are therefore suitable for frequent changing operation sites. The welding fume is collected directly at the point of discharge and can usually be extracted at one or several workplaces simultaneously.
The welding fume collector DUSTOMAT 4 is a frequently proven extraction solution for nearly any scope of application in the medium performance range.
Compact models like the SRF T are portable and can be connected directly to the welding torch.
The mobile SRF K is suitable for the extraction of large amounts of smoke and provides air-return back into the work area due to its 99.9% collection efficiency.
High-vaccum welding fume filters such as the SRF SK provide even with longer distances to the point of discharge an optimal extraction solution.
Stationary Welding fume filters
Welding fume filters with a stationary set-up can be installed directly next to the processing machine and provide a direct extraction solution at welding torches.
The COMPASOG SR has due to its two-level filtering system a very high separation performance.
The W3 certified MOBEX F can even be used for welding fume extraction of high-alloyed steels.
The modular welding fume filter systems WELDEX FE are ideal for large amounts of air up to 120.000 m³/h and are suitable for direct extraction of welding fumes.
The IFA-certified welding fume collectors of the DUSTMAC F series are used in a modular set-up and can be used as such in combination to create a welding fume filter system that can handle any required air volume.
Hall ventilation systems
In order to comply with legal regulations, it is in some instances indispensable to install completely integrated systems in addition to local extraction devices. In this case the free-standing Plug & Play hall ventilation system FILTOWER-F is suitable to capture welding fumes in production halls without ductwork.
Alternatively, the welding fume collector WELDEX FE has proven to be a very efficient hall ventilation system.
