Welding Fume Particle Separation Efficiency
The weld fume particle separation efficiency measures how well a filter removes fine particles from the fume. A high level protects breathing air better and helps meet legal standards.
Physicochemical mechanism of action
The welding fume particle separation efficiency (PSE) indicates how effectively a filter removes fine particles from the fume. It's given in percent and measures the reduction in particle density compared to unfiltered fume.
Metallurgical relevance & risks during welding
A low PSE can lead to increased airborne contaminants, which can cause health problems. Additionally, fume with fine particles can soil workpiece surfaces and impair weld quality.
Workshop practice & instructions
To ensure a high PSE, use high-quality filters in the extraction unit. Ensure filters are regularly maintained and replaced when necessary. A typical welding fume particle separation efficiency should be at least 95 % to meet legal limits.
