Dr.Air KH-4800 Portable Welding Fume Extractor

Welding dust is one of the types of dust with a high potential for pollution and requires timely treatment measures. Welding dust is generated in workshops that use mechanical welding equipment, metal grinding machines that create large sparks, and welding fumes in factories or industrial workshops.

Welding Fume Treatment with the Dr.Air KH-4800 Mobile Fume Extractor

From an aesthetic perspective:
The Dr.Air KH-4800 mobile welding fume extractor has a solid design with one extraction hood. The extraction arm can be easily adjusted to the closest position to the welding fume source, combined with a spark shield before directing the air into the machine for filtration.

The machine uses HEPA filter technology with high dust-filtration efficiency.

Formation of Welding Fume Particles

Welding fume particles are formed mainly from the evaporation of metal and welding materials when melted. As they cool, the vapor condenses and reacts with oxygen in the atmosphere, forming fine particles. About 90% of the fumes generated from materials will be burned off.

The fumes produced also vary depending on the welding process: MMA and FCAW (wire arc welding) generate more fumes due to burning the flux coating and welding rods rather than the base metal. In gas welding, the fume concentration comes mostly from the base metal.

These particles have sizes ranging from 0.01 to 1 micron. Such particles are highly toxic to workers. The smaller the particles are, the more dangerous they become. Other gases generated during welding can also pose serious risks if the workshop is not properly ventilated.
