Fume extraction in welding shops
There is no single “right” method for managing welding fumes—even in the smallest welding shops. A successful outcome is always the sum of multiple components. The key is to understand the issue from a system-level perspective: providing clean and fresh breathing air is the responsibility of the legally required ventilation system.
Fume extraction and filtration units remove contaminants from the air by continuously filtering and recirculating it, but they do not currently affect the calculation basis (m³ capacity or pressure) for the official ventilation system. However, in dirty environments, they do contribute to the efficient operation of heat recovery systems and significantly extend the cleaning intervals for heat exchanger elements. Our recommendation is to treat these two systems separately.
The first decision is usually the pressure level of the system—whether to operate with a low-pressure or high-pressure setup. If many fume extraction guns or precise local extraction points are in use, a high-pressure system can yield excellent results. One of its main advantages is the use of small-diameter ducting, which is both easy and cost-effective to install.
Remember: the closer the extraction point is to the source, the less airflow is needed. Moving the extraction nozzle from 10 cm to 40 cm away can increase the required airflow roughly tenfold!
