Welding Fume Treatment Process of the Dr.Air KH-3600 Plus

The Dr.Air KH-3600 Plus operates on the principle of extraction and filtration, effectively removing harmful welding fumes to protect workers and maintain clean air.

Process:

Fume Extraction
The high-power fan creates strong suction, pulling welding fumes into the machine through flexible extraction arms.
The arms can be adjusted in angle and position to capture fumes directly at the emission source, ensuring maximum efficiency.

Fume Filtration
Contaminated air passes through a multi-layer filtration system:

  • Pre-filter: Removes large dust particles, fibers, and coarse contaminants.

  • Main filter: Typically uses HEPA or Nano filtration technology, capable of capturing ultrafine particles, including hazardous metal particulates in welding fumes.
    The filter has a large surface area to improve filtration efficiency and extend service life.

Clean Air Discharge
Filtered clean air is released back into the environment, ensuring a healthy working atmosphere.
