Welding fumes may cause health problems and negatively affect production. The result is reduced capacity, reoccurring disturbances and eventually decreased profit. Not only are welders at risk in unsafe environments, the production equipment, as well as end products, are negatively affected from the lack of adequate safety measures. Automated welding equipment such as robots - and the operators - can be subject to residual welding fumes and also need to be protected. Good safety and health is good business. 

Letting the extraction system run when not in use is a big waste of energy. Not only the fan motor energy, but cost of heating or cooling make-up air to replace the air exhausted outside. With a Nederman fan inverter control system, the airflow extracted is constantly adjusted to the minimum required, reducing plant operating costs.

For additional savings, easy-to-program timers, machinery use sensors, and automatic dampers (motorized or pneumatic) can be combined at the extraction points to further reduce unneeded air extraction. This improves system efficiency, extends maintenance intervals, and reduces filter cleaning cycles and filter replacements, resulting in lower operating cost and more facility uptime.
