Soldering Fume Extractor:
Soldering process may produce fumes that are hazardous and it to be necessary to catch the harmful smoke before reaching spread in Atmosphere. In addition, using flux containing resin (also called colophony) produces solder fumes that, if inhaled, can result in occupational asthma or make existing asthmatic conditions worsen. The fumes can also cause eye and upper respiratory tract irritation.
It is not expected that occasional soldering activities that take place within areas that are well ventilated or have additional local exhaust ventilation will pose an occupational hazard to the employee.
Melted or heated silver and gold can produce fumes – and it’s never a good idea to breathe any fumes or dust created when metal is worked. Over-exposure to silver fumes is unusual, though, because it can permanently change the colour of one’s eyes and skin.
Solder fume can contain many of the compounds shown below, of which approximately 99.5% are particles and 0.5% are gases. The design of any filtration system should take these facts into account as these fumes can pose a serious danger to the health of employees who are exposed to them.
Hazardous Gas & Dust :
- Lead oxide
- Carbon monoxide
- V.O.C (volatile organic compounds)
- Abietic acid
- Pimaric acid
- Aliphatic aldehydes
- Hydrochloric acid
- Isopropyl alcohol
To Extract the harmful hazardous smoke to be suck and Filter in mandatory to all soldering process.
TOXICOLOGICAL EFFECTS OF COLOPHONY:
Solder fume is one of the top causes of occupational asthma in the workplace. This is caused by respiratory sensitisers, which are substances that when breathed in can trigger an irreversible allergenic reaction in the respiratory system. Once this sensitisation reaction has taken place, further exposure to the substance, even the tiniest trace, will produce symptoms.
Once a person is sensitised, continued exposure can result in permanent damage to the lungs and increasingly severe symptoms. Because of this, some people have been unable to return to soldering work for the rest of their lives. Pregnant women should be aware of potential hazards to the fetus from many of the chemicals used in jewellery processes and should avoid exposure to metal fumes and dust in particular.
- “All soldering should be done with local exhaust ventilation”
“Source capture ventilation, local ventilation, and general mechanical ventilation (With filtration) can provide long term permanent solution”
CLEANTEK Soldering Fume Extractor is manufactured for heavy-duty industrial use to capture the pollution at source. Unit attached with the frame of a portable wheel to move wherever fume extraction is required. Fume extractor consists of 4 stage filtration with a modern electrostatic filtration system. This electrostatic filtration requires periodic cleaning only. The Extractor Features four-stage filtration and purification. System controlled by a control panel operated at 415 V / 50 Hz.
How it works:
Contaminated air is drawn by the suction motor threw the washable stainless steel mesh filter which traps the large dust particles. Then the air pass through fine filter fabric, here fine dust particles are filtered. Remaining airstream pass into the strong electric field (12.5 Kv to 13 Kv) (Ionizing section) where particulate receives an electrical charge. The charged particles then pass into a collector plate section made up of a series of equally spaced parallel plates. Each alternate plate is charged with the same polarity (6 Kv -7Kv) (Collecting section) as the particles, which repel, while attract and collect the contaminants. The contaminants are held in these plates until they are washed away. Further air pass into the gas phase activated carbon filter. Here the toxic gases are absorbed by the activated carbon. Then pure air sent out threw Exhaust line.
