Zero-Smog Series Mobile Fume Extraction Filter Systems www.wellerft.comWhy Fume Extraction Many work environments today, including soldering, adhesives, welding and laser applications, create particles and gases that It is important to use the correct safety equipment to remove can be harmful to the work place and the environment. Most these hazardous substances. Fine particles are more dangerous people thought that the move to leadfree soldering would be to inhale than big particles as they get caught more easily and more nature friendly. In reality leadfree soldering smoke block the alveoli in the lungs. emissions contain more breathable fine dust particles. More smaller particles are produced due to the higher working To protect the operator it is important to use an extraction sys- temperatures required and because more flux is used in the tem that is able to separate these particles and gases and then soldering process. re-circulates the cleaned air back into the work place. This saves energy and reduces energy costs. In many countries legal regulations governing clean air in the work place require that hazardous substances are removed The smaller the particles are, the deeper they penetrate into from the air in order to avoid harmful effects on people and the respiratory system machines. The deeper the particles penetrate, the higher are the health risks The smallest particles travels via alveoli into the bloodstream Fine dust accumulation in the human body Fibres 10 m Pollen 10 m Bacteria Pigments 5 m Fine dust filter F7 / M5 Smog Asbestos dust > 1m Wide band gas filter E 12 Viruses > 0,5 m Gasfilter Gas 90 minutes soldering with leadfree solder wire before after 3
