Compensation device for welding exhaust air
A welding fume compensation system is a device that automatically supplies conditioned make-up air to balance the negative pressure in a workshop and prevent drafts. It ensures the proper operation of the extraction components.
Physical-chemical mechanism of action
The welding fume compensation system works by supplying conditioned make-up air to the workshop. This balances the negative pressure created by the exhaust system and prevents drafts that would otherwise be drawn in through openings or fans.
Metallurgical relevance and risks in welding
Without a compensation system, the negative pressure in a workshop can become so high that drafts occur. These drafts can bring in unswept particles and fine dust, which can degrade air quality and affect welding results. In addition, high negative pressure can cause problems with the extraction components, such as reduced performance or fan failure.
Workshop practice and procedures
To set up the compensation system effectively, adjust the make-up air flow to balance the negative pressure in the workshop. This can be done by adjusting the fan speed or the damper settings. A typical air flow is about 10-20 m³/h per square meter of floor area. Regularly inspect and maintain the compensation system to ensure it operates correctly.
