Dr.Air KH-3000 Portable Welding Fume Extractor

Welding fumes are known as the vaporization of metal and molten filler material. When the welded material cools down, the vapor condenses and undergoes oxidation in the atmosphere, forming fine particulate matter. Approximately 90% of the fumes produced during welding are burned-off substances.

Two main types of fumes are generated during MMA and FCAW welding. Most of the fumes come from the burning of flux coatings and electrodes rather than from the welded material itself. Welding fume particles typically range from 0.01 to 1 micron, and the smaller the particles, the more dangerous they are.

Welding Fume Treatment Process of the Dr.Air KH-3000

1. Fume Extraction
   The high-power fan generates strong suction, drawing fume-contaminated air into the machine through the extraction hose, which can be adjusted to the welding source.

2. Filtration

   • HEPA Filter: Welding fumes pass through the HEPA filter, where ultrafine particles, including toxic metal dust, are trapped.

   • Filtration efficiency of up to 99.97% for particles ≥0.3 micron.

3. Clean Air Discharge

   • After filtration, clean air is released back into the environment, ensuring a safer working atmosphere.
