The fact that fumes from soldering are not “too healthy” is probably obvious to everybody. Even without big studying of a chemical composition of a smoke arising at hand soldering, everybody who ever soldered knows, that a single breathe-in is enough to irritate us to coughing. The cause of fumes formation is mainly a flux exposed to a high temperature of a soldering tip. Besides a whole range of irritating gases, also dangerous small particles get to air. Their size is roughly 0.2-2.5 um, and they have a tendency to accumulate in lungs and the human body is able to eliminate them only with a big effort.
That´s why any air exchange on a workplace is always welcome. A good workplace ventilation is a big plus, however the key is to get fumes uprising at a soldering tip “away” from the range of an operator.
A simple solution is to use a table filter like for example ZD-953, which can take away majority of fumes and a carbon filter will clean the air partially. However such a solution has many disadvantages mainly because a thin filter used in these devices looses its efficiency very quickly and its absolutely unable to catch small dangerous micro-particles. Moreover this solution is quite noisy, that´s why this type of filters in suitable for developers and amateurs who solder only occasionally and for a short time.
Two solutions are usually usable for a professional usage:
• fumes extraction at a soldering tip – very effective, but it´s usually necessary to have a suitable adapter for various soldering tools you use
• so called “volume” fumes extraction, quite similar to a home vacuum cleaner :)
Volume extraction is the most universal solution independent on a type of a soldering station or tool. In contrast to a home vacuum cleaner the station doesn´t have to overcome so high aerodynamic resistance, that´s why the power and the noise in incomparably lower. The biggest advantage is the fact that the extraction station placed next to a table is big enough to allow usage of big and sufficiently efficient filters usually consisting of two stages.
A pleasant novelty for everyone who cares for its health is the fumes extraction station Zero Smog EL, representing currently the most economical solution from company Weller. Despite a price affordability, the station is fully comparable to more expensive types and uses a top class brushless EC fan (turbine). Zero Smog EL is a complete set including extraction hose and a nose able to clean up to 150 m3 of air per hour. A great feature is a possibility to set the power of a station in 4 levels. After a period of usage a logical question may arise – is it already necessary to exchange a filter or not yet? No problem – the station monitors pressure difference on the input/output of the filter and if necessary indicates the necessity of filter exchange itself.
Zero Smog EL is supplied a set for 1 workplace but separately it´s possible to buy another hose and arm for work at two workplaces at once.
Zero Smog EL can be found in our standard stock offer.
