Why Use Fume Extraction Systems by Matedex

Why Use Fume Extraction Systems

Many work environments today, including soldering and adhesives application, create particles and gases that can be harmful to the work place and the environment.
Most people think that the move to leadfree soldering would be more nature friendly.
In reality leadfree soldering smoke emissions contain more breathable fine dust particles. More smaller particles are produced due to higher working temperatures required and because more flux is used in the soldering process.
In many countries legal regulations governing clean air in the work place require that hazardous substances are removed from the air in order to avoid harmful effects on people and machines.

It is important to use the correct safety equipment to remove these hazardous substances. Inhaling fine particles is more dangerous than big particles as these get caught more easily and block the alveoli in the lungs.
To protect the operator it is important to use an extraction system that is able to separate these particles and gases and then re-circulates the cleaned air back into the work place.
This also saves energy and reduces energy costs.

1  Long term exposure to airborne particles and gases can cause permanent damage to human beings.

2  Thousands of workers all over the world contract occupational lung- and other diseases, including cancer, each year. They develop them because they breathe in too much dust, fumes or other airborne contaminants at work.

3  At least 20 % of the employees in the soldering area indicate clinical symptoms of asthma.

4  Occupational asthma is a major issue in electronics manufacturing because when a person has developed occupational asthma he/she has to be moved from that working area.

5  Breathing with occupational asthma feels like breathing through a straw.

30 minutes exposure to airborne particles and gases per day is enough to cause health problems. 30 minutes exposure per day means approximately 110 h/year or 14 workdays with continuous exposure to hazardous gases and particles. WellerFT made a soldering test with a net mounted in the nozzle. 90 minutes later the net was totally clogged up (see pictures below).

6  When asthma symptoms have developed, they are permanent and irreversible.

7  Almost everybody who works in an industrial environment comes in contact with chemicals which contain a solvent.

8  Most dangerous gases are invisible for the naked eye.

9  For people with heart diseases, short term exposure to hazardous airborne particles, can be linked to heart attacks and abnormal heart rhythms.

10  The combination of being exposed to both gases and airborne particles is more dangerous than only being exposed to gases.


Weller FT Electronic particles
   Lead free soldering produces up to 250 % more particles in the breathing zone than leaded solder. As much as 700 million small particles per cubic meter are produced, which can be transported into the alveoli.


Weller FT solvents
   Fumes from organic solvents can cause damage to the nervous system, with symptoms of reduced sensibility, restless legs and arms.


Weller FT Laser Line
   In all application areas where laser tools are being used, the emission of particles and gases is unavoidable. The diffusion of the produced emissions however has to be prevented as they are hazardous to health and can also settle as damp on sensitive components.
