Filtration Systems and Hazardous Gases and Particles... Continued from previous page


ma they must be moved from that working area. Once a person devel- ops asthma, the symptoms are permanent and irreversible. Almost everyone who works in an industrial environment comes


in contact with chemicals that contain a sol- vent. Most harmful gases are invisible to the naked eye. For people with heart diseases, short-


term exposure to hazardous airborne parti- cles can be linked to heart attacks and abnormal heart rhythms. The combination of being exposed to both gases and airborne particles is more dangerous than only being exposed to gases.


Invisible Particles While no one likes smoke and flux fumes


in their face, it’s the invisible- to-the-eye particles and gas that cause even more damage and embed even deeper into the lungs. The Internet abounds with the dangers of inhaled gases and chemicals. The more you read, the scarier it gets. Many people assume lead-free solder is the answer to our health concerns, but that has just resulted in even more aggressive fluxes and fumes all burning off at higher tempera- tures, creating even more residues. Air in the breathing zone


from lead-free hand soldering can contain more than 20 mil- lion particles in the range of 0.3 to 1 micron in size. It is the combination of particles and gases that is the most danger- ous. Gases stick to the particle, ending up in the alveoli deep in the lungs and causing inflam- mation and lung damage. This is exactly what soldering smoke is. This is why a good filter sys- tem needs to be able to filtrate both particles and gases and why the filter must be replaced in a timely manner. There are many and varied


markets with gases, fumes, smoke, or small particles air- borne in the workplace. These markets need fume extraction under legislation pertaining to that country. The damage caused by repeated inhalation of foreign substances is severe and often permanent.


Weller’s Solution Weller helps the workforce


breathe easier with best-in- class air filtration solutions. Weller began working in fume extraction in the 1990s. It later acquired Filtronic, a reputable filtration brand and market leader in Europe at that time. The company had an abun- dance of skill, knowledge, and expertise, and a focal point was the filter element itself. Its units tend to have large


gas filters that ensure enough dwell time for the physical and chemical interactions to take place between media and con- taminants. The other plus side of the filters being large is that

they require less frequent filter changes. Weller has a range of filtration units and filter types to cover many varied application requirements. Weller Tools even has experts that can advise on the correct fil-


ter media for a customer’s bespoke chemicals. The company’s prod- ucts are packed with other features like con- nectivity with its soldering stations and other devices and the filtration units operate at low noise levels. Extraction systems from Weller Tools


provide a systematic solution to any applica- tion. Its technology eliminates dangerous fumes and particles, leaving clean air behind.
