Activated Carbon Fine Particle Filter
An activated carbon fine dust filter adsorbs gaseous pollutants and filters respirable particles from the welding exhaust air stream. This improves air quality and protects the respiratory tract.
Physical-Chemical Mechanism of Action
Activated carbon has high adsorption capacity for gaseous substances like nitrogen dioxide (NOx) and carbon monoxide (CO). The fine dust filter captures respirable particles with a diameter of 0.1 to 2 micrometers. This happens through mechanical deposition on the filter surface.
Metallurgical Relevance & Welding Risks
Without an activated carbon fine dust filter, welding work generates high concentrations of gaseous pollutants and fine dust, which are hazardous to the respiratory tract. This can lead to chronic lung diseases. A faulty filter system can also cause insufficient air supply and poor visibility in the work area.
Workshop Practice & Instructions
Use an activated carbon fine dust filter with an adsorption capacity of at least 10 g per liter of air. Exhaust air velocity should be between 0.5 and 2 m/s. Change the filter every 3 to 6 months or when it is full. Ensure the filter is installed correctly and has no gaps.
