Measures

There are different possible ways of capturing harmful emissions

1. Source extraction integrated into the welding torch 

• Integration into the system
• Low air flow
• Good to very good capture rate

2. High vacuum - source extraction system

• Efficient source extraction through suction nozzles
• Good capture rate up to a distance of 150 mm
• Simple connection to the extraction system by hoses

3. Low vacuum - Source extraction system

• Easy to use with flexible extraction arms with ease of movement  
• Freely positionable hoods 
• High capture rate at up to 400 mm away

4. Exhaust hood

• Adjustment of the exhaust hood to the respective work area
• Capture of the entire thermal flow from the weld area 
• Very low negative pressure required

5. General ventilation systems

• Two methods: Displacement ventilation (layered ventilation) or mixed air ventilation
• Extraction is carried out at a height of 4-6 m
• To complement the methods already mentioned or if other methods cannot be used
